Ionization-Excitation of Helium-Like Ions at Compton Scattering

Ionization of helium-like ions with simultaneous excitation of the ns -states due to photon scattering is considered. The differential and total cross sections of the process are calculated to leading order of perturbation theory with respect to the electron–electron interaction. The formulas obtain...

More Information
Summary:Ionization of helium-like ions with simultaneous excitation of the ns -states due to photon scattering is considered. The differential and total cross sections of the process are calculated to leading order of perturbation theory with respect to the electron–electron interaction. The formulas obtained are applicable in the nonrelativistic energy range far beyond the ionization threshold.
