Photoelectric Cross Sections in the keV Range

Abstract

Photoelectric cross sections have been computed using bound-state wave functions and potentials from a relativistic Dirac-Slater self-consistent-field program and numerical integration for the continuum wave functions and the matrix elements. Results for aluminum in the range 1-150 keV and for uranium in the range 80-150 keV are compared with existing experimental and theoretical data, with particular emphasis on the angular distributions.
