Atomic and ion properties calculated in the Hartree-Fock-Slater quantum-statistical model are used in the direct calculation of the differential and total cross sections of electron impact ionization of singly ionized oxygen and nitrogen atoms by the distorted wave approximation. The convergence of the cross sections justifies the applicability of the approximation for calculating the cross sections for impact ionization of ions by electrons in gas-plasma formations. The calculated cross sections are compared with analytical approximations and available experimental data. The calculation results show that the proposed method gives reliable results, which, combined with the applicability of the Hartree-Fock-Slater model in a wide range of temperatures and densities, allows it to be used in a wide range of energies and ion charges.
Keywords: collisional ionization, cross sections of atomic processes, distorted wave approximation, quantum statistical models of plasma.
