Abstract
Nonideal plasma screening effects on the occurrence time advance for the elastic electron–ion collisions in classical nonideal plasmas are investigated using the eikonal method. An effective pseudopotential model taking into account the plasma screening and collective effects is applied to describe the electron–ion interaction potential in nonideal plasmas. It is found that the nonideal effect reduces the occurrence time advance. The scattering occurrence time gets stronger time advances with increasing the scattering angle. For small scattering angles, the domain of the nonideality plasma parameter (γ) for the minimum occurrence time advance is found to be 1<γ<3.5.
