Atomic subshell photoionization cross sections and asymmetry parameters: 1 ⩽ Z ⩽ 103

Atomic subshell photoionization cross sections and asymmetry parameters are calculated with the Hartree-Fock-Slater one-electron central potential model (dipole approximation) for all elements Z = 1–103. The cross-section results are plotted for all subshells in the energy region 0–1500 eV, and cross sections and asymmetry parameters are tabulated for selected energies in the region 10.2–8047.8 eV. In addition, more detailed graphs are given for the 4d (Z = 39–71) and 5d (Z = 64–100) subshell cross sections in the vicinity of the Cooper minimum. These data should be particularly useful for work based on spectroscopic investigations of atomic subshells using synchrotron radiation and/or discrete line sources.
