CROSS-SECTIONS FOR ELECTRON-SCATTERING ACCOMPANIED BY IONIZATION OF INNER-SHELLS

A method is presented to describe the electron scattering process at a n ionization of inner-shell electrons.' The differential cross-section with the energy transfer and the momentum transfer is calculated usin g the expression of the generalized oscillator strength. This cross-se ction and the total ionization cross-section are fairly close to the r esults obtained by the Gryzinski equation. The photo-absorption cross- section obtained by the present treatment shows good agreement with th e experimental data in a wide range of the photon energy. Based on the present treatment, the scattering angle distribution of the primary e lectron is calculated.
