Abstract

Cross sections of 1s-, 2s- and 2p-ionization by electron impact and energy distributions for the knocked-off electrons are calculated in first Born approximation with Pauli-Fock wave functions for the second-row atoms from Li to Ne. Analytical formulas approximating knocked-off electron energy distributions for wide intervals of incident electron energies are suggested.
