摘要

Abstract

Dynamically screened three-Coulomb-wave model(DS3C) is used to study the single ionization of the 3S orbital of sodium by electron impact.Triply differential cross-sections(TDCSs) are calculated in doubly symmetric geometry at excess energies of 6,10, 15,20,30,40,50 and 60 eV using a parameterized optimized effective potential.Comparisons are made between recently experimental data and theoretical predictions of the three-Coulomb wave function(3C) approach and distorted-wave Born approximation(DWBA). The angular distribution of the present TDCS is found to qualitatively reproduce the reported experimental data.It is shown that dynamically screened effects are important in this geometry.
