Abstract:
We consider the inelastic high-energy photon scattering on heliumlike ions in the
ground state, which results in ionization accompanied by simultaneous excitation of the
residual ion. 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.
