摘要: Photoionization of helium-like ions accompanied by the excitation residual ion to nl-state is considered. Calculations are made in first-order perturbation theory electron-electron interaction using Coulomb wavefunctions as zeroth approximation. Formulas derived for ionization cross sections exhibit scaling behavior target nuclear charge Z and principal quantum number n. Numerical calculations performed entire nonrelativistic energy domain. Simple power expansions Sommerfeld parameter ξ obtained high- low-energy limits. The results compared with experiment.
