Debye-screening effect on electron-impact excitation of helium-like Al11+and Fe24+ions
文献摘要：
Debye-screening effects on the electron-impact excitation(EIE)processes for the dipole-allowed transition 1s2 1S →1s2p 1P in He-like Al11+and Fe24+ions are investigated using the fully relativistic distorted-wave methods with the Debye-Hückel(DH)model potential.Debye-screening effects on the continuum-bound(CB)interaction and target ion are discussed,both of which result in reduction of EIE cross sections.This reduction due to screening on the CB interaction is dominant.The non-spherical and spherical DH potentials are adopted for considering the screening effect on the CB interaction.It is found that the spherical DH potential could significantly overestimate the influence of plasma screening on EIE cross sections for multielectron He-like ions.
