Strongly inelastic scattering of electrons by ions in near-resonance laser field: Core polarization effects on the line shape of the process

Core-polarization-induced effects on the spectral cross-section of the strongly inelastic electron scattering by ions in the near-resonance laser field are investigated theoretically. The main attention is given to the peculiarities in the line shape of the process cross section, which are due to the interference between polarization and static scattering channels. It is shown that in the case of strongly inelastic electron scattering this interference is subjected by the penetration of the incident electron in the target core. This penetration causes the dependence of the spectral cross-section on a number of involved parameters of the process.
