Renormalized dynamic charge shielding on the electron-atom collision: Eikonal analysis

Abstract

The influence of the dynamic renormalization plasma shielding on the electron-atom collision is investigated in a dense strongly coupled electron system. The semiclassical eikonal method and effective interaction potential are employed to obtain the eikonal scattering phase shift and eikonal collision cross section as functions of the Debye length, impact parameter, projectile energy, and thermal energy. It is found that the renormalized dynamic charge shielding effect enhances the eikonal collision cross section. The variation of the dynamic renormalization shielding on the electron-atom collision is also discussed. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4792248]
