Abstract
Plasma and quantum screening effects on the occurrence time for electron-ion scattering in dense high-temperature plasmas are investigated using the eikonal method. An effective pseudopotential model taking into account both the quantum-mechanical effects and the plasma screening effects is applied to describe the electron-ion interactions in dense high-temperature plasmas. The quantum and plasma screening effects on the elastic electron-ion scattering significantly reduce the time advance for small scattering angles, i.e. the scattering occurs later. However, the time advance is increased with increasing scattering angle due to the quantum and plasma screening effects.
