Subshell Photoionization Cross Sections and Ionization Energies of Atoms and Ions from He to Zn
Abstract
Partial photoionization cross sections of atoms and ions from He to Zn for all subshells nl of ground-state species are calculated with the Hartree-Dirac-Slater method for photon energies E ≲ 100Eth, where Eth is the photoionization threshold. The cross sections are fitted by simple analytic expressions for E ≲ 50 keV, and the ionization energies are fitted by simple polynomials of atomic number Z and number of atomic electrons N. The fit parameters are tabulated.
