Electron transfer in proton-hydrogen collisions under dense quantum plasma

The effects of dense quantum plasma on 1s → nlm charge transfer, for arbitrary n,l,m, in proton-hydrogen collisions have been studied by employing a distorted wave approximation. The interactions among the charged particles in the plasma have been represented by modified Debye-Huckel potentials. A detailed study has been made to explore the effects of background plasma environment on the differential and total cross sections for electron capture into different angular momentum states for the incident energy in the range 10–1000 keV. For the unscreened case, our results agree well with some of the most accurate results available in the literature
