Collective and Plasma Screening Effects on Electron Transfer Processes in Nonideal Plasmas

Collective and plasma screening effects on the maximum principal quantum number and the maximum internuclear distance in electron transfers in nonideal plasmas are investigated. An effective pseudopotential model taking into account collective and plasma screening effects is applied to obtain the interaction potential and screened effective charge in nonideal plasmas. The screened over the barrier model is applied to obtain the electron capture radius and the maximum principal quantum number of the final state of the transferred electron. The results show that the electron capture radius is more sensitive to the collective effect rather than the plasma screening effect. The electron capture radius is found to increase with increasing nonideality plasmas parameter. It is also found that the maximum principal quantum number of the final state of the electron increases with increasing nonideality plasma parameter and reciprocal Debye length
