Collisional Rates and Cross-sections Calculated by Hartree-Fock-Slater Model
On the basis of quantum-statistical model of self-consistent field - the Hartree-Fock-Slater model for the average atom - the universal procedure for calculation of rates and cross-sections of collisional processes in plasma of multicharged ions is developed. The calculations for Xe and Sn plasmas are fulfilled. Comparison with experimental data and widely used methods is carried out. It is shown that for some Xe ions the contribution of indirect processes to ionization rate may be very important. The influence of density effects on excitation and ionization cross-sections is analyzed.
