摘要
High-frequency photon scattering by a two-electron ion with excitation of singlet autoionization states located below the first excited level of the respective one-electron ion are considered, Angular distributions of scattered photons and total cross sections are calculated for transitions to 2s2p(P-1) and 2p(2)(D-1) autoionization states (AIS) from the ground state of helium-like ions (the transitions to two lower S-1 AIS were investigated earlier). In the zero approximation electrons are described by Coulomb functions and the interelectron interaction is taken into account in the first perturbation order.
