Photoionization cross-section calculation of atomic tungsten.
Physical Review A, 1993A photoionization cross-section calculation of atomic tungsten is performed in the formalism of many-body perturbation theory for photon energies ranging from the ionization threshold of tungsten to 150 eV. Nonrelativistic orbitals are used in the basis set and relativistic corrections are included.

Atomic photoabsorption cross sections
Journal of Quantitative Spectroscopy and Radiative Transfer, 1967Abstract Results are reported of extensive calculations on atomic photoabsorption cross sections by the statistical method in various approximations, based on developments presented in previous papers. A closely spaced family of photoabsorption cross sections emerges which, on scaling with regard to atomic numbers, represents in an unified manner the

Positron-atom doubly differential ionization cross sections
Physical Review A, 1994Doubly differential ionization cross sections for positron impact on argon atoms were determined by energy- and angle-resolved measurements of ejected electrons in time correlation with the produced ions. Corresponding measurements with incident electrons were made for comparison.

Total atomic photoelectric cross-sections
Il Nuovo Cimento B Series 10, 1969Total atomic photoelectric cross-sections have been obtained by the subtraction technique for the elements Cu, Mo, Ag, Sn, W, Au, Pb and U in the energy region 20 to 1330 keV; and compared with the tabulated theoretical predictions of Schmickley and Pratt. It has been found that, in general, there is satisfactory agreement between the two.

A Survey of Photon Cross Section Data for use in EPICS2017
, 2018I have presented here my Survey of Atomic Photon Cross Section Data for use in EPICS2017. There are few original results of in this report; most of the original work was done by those who put together the compilations that I used; one being my own EPDL ...

Stopping cross-sections and atomic potentials
Radiation Effects, 1976Abstract A strong correlation is shown to exist throughout the periodic table : etween the Z 2 dependence of the electronic stopping cross-sections for 4He ions of a given velocity and the Z dependence of the atomic potentials at a certain radius. An empirical formula is presented which allows the extrapolation of stopping cross-section data for any ...
