摘要：A modified distorted-wave Born approximation （DWBA） method is used to calculate the triple differential cross sections （TDCSs） in a coplanar asymmetric geometry for the electron impact single ionization of a He （ls2） atom at intermediate and lower energies. The post-collision interaction and the polarization effect in （e, 2e） collisions of helium are considered in the calculations. The polarization potentials from the damping method and density functional theory （DFT） are compared. Theoretical results are compared with the recent experimental data.
A modified distorted-wave Born approximation (DWBA) method is used to calculate the triple differential cross sections (TDCSs) in a coplanar asymmetric geometry for the electron impact single ionization of a He (1s(2)) atom at intermediate and lower energies. The post-collision interaction and the polarization effect in (e, 2e) collisions of helium are considered in the calculations. The polarization potentials from the damping method and density functional theory (DFT) are compared. Theoretical results are compared with the recent experimental data.
