- "An expression for the charge-deposition distribution near the surface of a
semi-infinite medium irradiated by electrons." F. Alouani-Bibi, V.T.Lazurik,
Yu.V. Rogov and T. Tabata, IEEE Trans. Nucl. Sci. Vol. 46, No. 3, pp.
280-283 (1999) (doi: 10.1109/23.775528).
Abstract: On the basis of the characteristics
of electron transport, a semiempirical model has been developed to describe the
charge-deposition distribution due to knock-on electrons produced by
electron-electron interactions near the surface of a semi-infinite medium.
A criterion is provided for the thickness of the zone near the surface
where the charge deposition is essentially due to knock-on electrons. A
comparison between the charge-deposition distributions obtained by the
Monte Carlo method and the present model is made in the above zone. The
absorber materials considered are Be, C, Al and Cu, and the energies of
incident electrons are from 1 to 10 MeV. The advantages and limitations
of the present model in comparison with other analytic expressions are
discussed. (© 1999 IEEE)

evaluate secondary-electron yield by photons." V. Lazurik, V. Moskvin,
Y. Rogov, T. Tabata, IEEE Trans. Nucl. Sci. Vol. 46, No. 4, pp. 910-914
(1999) (doi: 10.1109/23.790702).
Abstract: In our previous paper [V. Lazurik,
V. Moskvin and T. Tabata, IEEE Trans. Nucl. Sci. 45, pp. 626-631 (1998)]
the average depth of electron penetration, Rav,
has been introduced as the average of the maximum depths on the trajectories of
electrons passing through a target. In the present work the dependence of
Rav on the angle of incidence of an electron beam has been
studied. A semi-empirical equation is derived to calculate
Rav as a function of angle of incidence. We
extend the study of Rav from using it to
characterize the average behavior of electron beams in a target to describing the
generation of secondary electrons by photon beams. It is shown that
Rav can be used in a wide variety of
applications in which the characteristic size of the spatial region of electron
production is important. (© 1999 IEEE)
- "Mirror reversal simply explained without recourse to psychological
processes." T. Tabata and S. Okuda, Psychonomic Bulletin & Review
Vol. 7, No. 1, pp. 170-173 (2000)
(Download PDF).
Abstract: This paper proposes a simple and
definitive solution to the mirror-reversal problem, "Why does a mirror reverse left
and right but not up and down?" The solution is given by combining the inversion
caused by the optical process of mirroring and the definition of the left-right axis.
Thus the left-right reversal of mirror images essentially does not involve
psychological processes, in contrast to the multiprocess hypothesis recently
proposed by Takano. (© 2000 Psychonomic Society, Inc.)
- "Approximation of charge-deposition density in thin slabs irradiated by
electrons." F. Alouani-Bibi, V. T. Lazurik, Yu. V. Rogov and T. Tabata,
Radiation Physics and Chemistry Vol. 59, No. 3, pp. 239-248 (2000) (doi:
10.1016/S0969-806X(00)00268-1).
Abstract:
Charge-deposition distributions in thin slabs irradiated by plane-parallel
electron beams are studied. The slabs considered are made of elements with
atomic numbers ranging from 4 to 79. The slab thicknesses are from 0.5 to
50 mg/cm2, and the electron beam energies
are from 1 to
10 MeV. Using a new Monte Carlo method (called the trajectory translation
method), data on the charge-deposition density have been obtained.
Theoretical analysis of these data has been performed. Based on this
analysis, a semiempirical model that describes charge-deposition
distributions in thin slabs has been developed. The results obtained by
the semiempirical model have been compared with those obtained by the
PENELOPE Monte Carlo code and show moderate agreement. (© 2000 Elsevier

H- with hydrogen molecules."
T. Tabata and T. Shirai,
Atomic Data and Nuclear Data Tables Vol. 76, pp. 1-25 (2000)
(doi: 10.1006/adnd.2000.0835).
Abstract: Analytic expressions fitted to
cross section data on collisions of H+,
H2+,
H3+,
H, H2,
and H- with
H2 are
given. The data used are those recommended by Phelps [J. Chem. Phys. Ref.
Data 19, 653 (1990)] and additional experimental data, when available,
up to the projectile energy of about 100 keV, including new kinds of
reactions not treated by Phelps. The analytic expressions are of the
semiempirical functional forms proposed by Green and McNeal [J. Geophys.
Res. 76, 133 (1971)] and modifications of these, thus making it possible
not only to interpolate but also to extrapolate the data to some extent.

- "Charge-deposition in
two-layer systems irradiated by electrons."
F. Alouani-Bibi, V. T. Lazurik, Yu. V. Rogov and T. Tabata,
Radiation Physics and Chemistry Vol. 60, No. 3, pp. 151-156 (2001) (doi:
10.1016/S0969-806X(00)00332-7).
Abstract:
On the basis of the data obtained by computer simulation and theoretical
analysis of charge-deposition density in single slabs located in vacuum
(Alouani-Bibi et al., 1999), a semiempirical model that describes the
charge-deposition distributions in two-layer systems irradiated by fast electron
beams has been developed. The slabs considered are made of materials with atomic
numbers from 4 to 79 and thicknesses from 0.5 to 50
mg/cm2 irradiated by electron beams with
energies from 1 to 10 MeV. Comparisons have been made of the results obtained by the
present model and those obtained by the PENELOPE code. Results of charge-deposition
distributions for different material combinations of the layers are also presented.

- "Analysis of a discrepancy in electron-beam dose comparison between chemical
dosimeters and a calorimeter."
Zong Yuda, Gao Juncheng, Tatsuo Tabata, Zhang Yanlia and Yang Yuandi,
Applied Radiation and Isotopes Vol. 55, No. 1, pp. 125-128 (2001) (doi:
10.1016/S0969-8043(00)00373-0).
Abstract:
A 2.1% discrepancy was reported from an electron beam dose comparison between
liquid chemical dosimeters and a water calorimeter. Two methods, depthÐdose
measurement in a sandwich phantom and the use of a semiempirical depthÐdose code
EDMULT, were used to analyze the depth-dose distributions in the dosimeters and
the calorimeter and to calculate their dose ratio. Results have shown that the
discrepancy can be explained by the difference in the effective detection
volume. (© 2001 Elsevier Science Ltd. All rights reserved.)

- "Oxygen tracer diffusion in the YBa2Cu3Oy superconductor."
S. Tsukui, M. Adachi, R. Oshima, H. Nakajima, F. Toujou, K. Tsukamoto and T. Tabata,
Physica C Vol. 351, pp. 357-362 (2001) (doi:
10.1016/S0921-4534(00)01640-3).
Abstract: The oxygen diffusion coefficient of
YBa2Cu3Oy
(YBCO) single crystals was determined by secondary ion mass spectrometry in a wide
temperature range from 628 to 1073 K. It was found that the slope of the Arrhenius
plot of the diffusion coefficient changes at the transition temperature from the
orthorhombic to the tetragonal phase (TP). The activation energies of oxygen in the
TP and the orthorhombic phase (OP) are 89.1±1.4 and 114.6±1 kJ
mol-1 in the ab plane, and 284±2.8 and
126.9±0.5 kJ mol-1 in the c axis
direction, respectively. In the OP, the activation energies in the ab plane
and the c axis direction are almost the same, but the diffusion coefficients
in the ab plane are larger than that in the c axis direction by more
than three orders of magnitude. At higher temperatures of the TP, the slope of the
Arrhenius plot in the c axis direction becomes larger and the diffusion
coefficient of the c axis becomes closer to that of the ab plane
towards the incongruent melting point of YBCO compounds. (© 2001 Elsevier

Bi2LnxCa2-xCu1Oz
(0.4≤x≤0.8, Ln = La, Pr, Nd, Sm, Eu and Gd) by laser ablation."

Physica C Vol. 361, pp. 189-194 (2001) (doi:
10.1016/S0921-4534(01)00411-7).
Abstract: We have prepared Bi-2001 thin films of
Bi2LnxCa2-xCu1Oz
systems (Ln = La, Pr, Nd, Sm, Eu and Gd) by the laser ablation method. In the
Bi2LaxCa2-xCu1Oz
system, the Bi-2201 films have been obtained in a wide composition range of
0.4≤x≤0.8, and the films with x<0.7 have been of the metastable
phase, which has never been reported to be synthesized by the solid state
reaction method. The film with x = 0.4 has shown the lowest resistivity in the
Bi2LaxCa2-xCu1Oz
system, and in the
Bi2LnxCa2-xCu1Oz
system (Ln = La, Pr, Nd, Sm, Eu and Gd), when x is fixed to 0.4, the film with
Ln = Nd has hsown the lowest resistivity. From the results of resistivity and
magnetic measurements, however, none of these films have been found to be
superconductive. (© 2001 Elsevier Science B. V. All rights reserved.)
- "Extrapolated ranges of electrons determined from transmission and
projected-range straggling curves."
Tatsuo Tabata, Vadim Moskvin, Pedro Andreo, Valentin Lazurik and Yuri Rogov,
Radiation Physics and Chemistry Vol. 64, No. 3 pp. 161-167 (2002) (doi:
10.1016/S0969-806X(01)00469-8).
Abstract:
Extrapolated ranges of electrons Rex,t and
Rex,p have been
determined from transmission and projected-range straggling curves, respectively.
Data on the two kinds of curve have been obtained by Monte Carlo calculations for
0.1-50 MeV electrons incident on elemental absorbers of atomic numbers between 4 and
92. The two sets of extrapolated ranges, as well as another set,
Rex,q,
determined from charge-deposition curves [Tabata et al., Nucl. Instr. Meth. B 119
(4), 463-470 (1996)], have been found practically the same. Appreciable differences
of Rex,t from
Rex,p and
Rex,q have been observed
only for electrons of energies below 2 MeV incident on absorbers of the highest
atomic numbers. The cause of these differences has been traced to the backscattering
of electrons from the incident surface, phenomenon affecting only
Rex,t among the extrapolated ranges determined
by the three methods. The fact that the extrapolated range is in most cases
independent of the method of determination establishes the usefulness of this
quantity. An analytic expression fitted to the Monte Carlo results of
Rex,t is given. (© 2002 Elsevier Science

- "Dose perturbations at high-Z interfaces in kilovoltage photon beams:
Comparison with Monte Carlo simulations and measurements."
Indra J. Das, Vadim P. Moskvin, Alireza Kassaee, Tatsuo Tabata and Frank Verhaegen,
Radiation Physics and Chemistry Vol. 64, No. 3 pp. 173-179 (2002) (doi:
10.1016/S0969-806X(01)00460-1).
Abstract:
Dose perturbations (backscatter dose perturbation factor, BSDF, and forward dose
perturbation factor, FDPF) near high Z material interfaces have been reported to
be intense and significant in kilovoltage photon beams. Validity of estimation of
dose perturbations is critical in the evaluation of radiation effects associated
with high Z interfaces. The magnitude of dose perturbations has been debated due
to limitations in the measuring devices (mainly window thickness and chamber
perturbations). Monte Carlo (MC) simulations have been proposed for the interface
effects but poor statistics in small spatial bins (1 mm) near the interface makes
MC data questionable even with a well designed code. A moving-window least-square
polynomial fit (MLPF) method is proposed to smooth MC simulated data. This method
is shown to be useful in achieving reasonable accuracy from statistically poor MC
data obtained within a reasonable computation time. The EGS4 and PENELOPE MC
simulated data at the interfaces between high-Z materials and a water phantom have
been used to calculate the BSDF and FDPF which differ significantly from the
measurements suggesting the necessity of further refinements in MC approaches and
better measuring devices for interface effects. (© 2002 Elsevier Science Ltd.

Abstract: Preparation of
Bi2(LnxCa2-x)Ca2Cu3Oz
thin films (0.3≤x≤0.7, Ln = Pr, Nd, Sm, Eu and Gd) by the laser ablation
method and their physical properties are described. These films have been of metastable
Bi-2223 phase, which had not been synthesized by the solid-state reaction method. In the
Bi2(PrxCa2-x)Ca2Cu3Oz
system, the resistivity of Bi-2223 films has increased with increasing Pr content x,
and the film with x = 0.3 has shown the lowest resitivity. When x is fixed to 0.3 in the
Bi2(LnxCa2-x)Ca2Cu3Oz
systems, the film with Ln = Sm has shown the lowest resistivity. However, the result of
the resistivity and magnetic measurements have shown that none of the films is
superconductive. (© 2001 Elsevier Science B. V. All rights reserved.)

- "Relationship between frames of reference and mirror-image reversals."
H. Yoshimura T. Tabata,
Perception Vol. 36, No. 3, pp. 1049-1056 (2007)
(doi:
10.1068/p5529).
Abstract: The mirror puzzle related to the perception of mirror images as left–right reversed can be more fully understood by considering an extended problem that includes also the perception of mirror images that are not left–right reversed. The purpose of the present study is to clarify the physical aspect of this extended problem logically and parsimoniously. Separate use of the intrinsic frame of reference that belongs to the object and one that belongs to its mirror image always leads to the perception of left–right reversal when the object has left–right asymmetry; on the other hand, the perception of left–right nonreversal is always due to the application of a common frame of reference to the object and its mirror image.

Abstract:
The difference between Kokame and Tabata hypotheses on the mirror problem comes from the rejection of the notion of the mirror image's intrinsic frame of reference by the former. However, this rejection has no solid freason.

T. Tabata,
Cognitive Sudies, (Part of Highlights: Mirror reversal; Part 2, Tabata's article) pp. 512-515 (2008) In Japanese.
Abstract:
When one uses intrinsic frames of reference separately for an asymmetric object and its mirror image, one perceives the mirror image as left–right reversed because of such a nature of the left–right axis that it is determined depending on the top–bottom and front–back axes. When one perceives the mirror image as left–right nonreversed, on the other hand, one is applying a common frame of reference to the object and its mirror image, obtaining the simple result of geometric optics.

Abstract:
All of Kokame's arguments against Tabata hypothesis are rejected as invalid. Instead, those arguments have clearly revealed that Kokame's hypothesis has no reason of its existence.

Abstract:
All of Takano's arguments against Tabata hypothesis are rejected as invalid. Thus the validity and solidity of Tabata hypothesis have been proved.

T. Tabata,
Cognitive Sudies, (Part of Highlights: Mirror reversal; Part 3, Takano's article) pp. 552-554 (2008) In Japanese.
Abstract:
Takano's hypothesis treats the psychological processes of mirror image perception; and Tabata's, its physical basis. Properly speaking, these two approaches should be united. To make the unification possible, however, the physical conception on which Takano's hypothesis is constructed should be rectified.

Abstract:
The experimental and computational work on the passage of fast electrons through
matter done at the Radiation Center of Osaka Prefecture (RCOP) is reviewed.
Related topics and problems to be solved are also described. The experimental
work treated is the measurement of backscattering coefficients and
charge-deposition distributions. Possible causes of discrepancies between
experimental and Monte Carlo results are discussed. Among the results of the
computational work, an empirical formula for the backscattering coefficient, a
semiempirical formula for the extrapolated range and the algorithms for
depthÐdose distributions are described. In Appendix, the work on interpolation
formulas for the continuous slowing-down approximation (CSDA) range is reviewed,
and a new formula is suggested. (Note: The 1st edition was published in 1983 as

Abstract:
Methods to formulate analytic expressions for atomic collision cross sections as
a function of projectile energy are described on the basis of the experiences of
the data compilation work for more than 20 years. Topics considered are the
choice of appropriate functional forms for the expressions and optimization of
adjustable parameters. To make extrapolation possible, functions to be used
should have the form with reasonable asymptotic behavior. In this respect,
modified Green-McNeal formulas have been found useful for various atomic
collision cross sections. For ionization processes, a modified Lotz formula has
often given a good fit. The ALESQ code for least-squares fits has been
convenient to optimize adjustable parameters in analytic expressions.

Abstract:
Institute for Data Evaluation and Analysis; Research Institute for Advanced Science and Technology, Osaka Prefecture University; Shanghai Applied Radiation Institute, Shanghai University; and Department of Radiation Oncology, Indiana University School of Medicine contributed a newly frozen version of EDMULT. Version 6.4 evaluates depth-dose distributions produced by plane-parallel electron beams normally incident on one- to six-layer slab absorbers. EDMULT is based on an analytic expression of the depth-dose curve in semi-infinite
medium and a simple model of electron penetration through a multilayer absorber. The effect of the different medium beyond an interface is accounted for by the difference of backscattering, which is evaluated by considering the branching of electron beam into transmitted and backscattered components. . . .
