Abstract
The inelastic high-energy photon scattering on helium-like ions in the ground state, which results in ionization accompanied by simultaneous excitation of the residual ion, has been considered. Nonrelativistic perturbation theory is employed as a method. The cross sections of the process for transitions into the ns and np states are deduced in the analytical form. A comparison of our results with those of approximated calculations is given.
