Abstract

Theoretical cross sections values for electron capture by proton impacting on methane and silane molecules are presented, based on the multi-reference single- and double-excitation configuration interaction calculation of electronic structures of collision intermediates, and compared with the available semi-empirical formulas recommended for fusion plasma simulations. The current results may apply not only to the simulations of fusion edge plasmas, but also plasmas of technological interest.
