Plasma screening effects on occurrence time for electron-ion scattering in strong coupled plasmas

Abstract

Plasma screening effects on the occurrence time for the elastic electron.ion scattering in strongly coupled plasmas are investigated using the ion-sphere model. For small scattering angles, the occurrence time advance is found to be significantly reduced with the decrease in the strength of the plasma screening. For strong plasma screening cases, the occurrence time advance is found to decrease with an increase of the scattering angle. However, for weak plasma screening cases, the occurrence time advance is increased sinusoidally with the increase scattering angle.
