Abstract

Cross-Sections for single electron capture by protons He+ and He2+ ions from Na  atoms have been calculated in the Modified Binary Encounter Approximation. The  Hartree –Fock velocity distribution has been taken into account throughout the  calculations. The angular divergence factor has also been considered. The present  calculations have fairly good agreement with the experimental observations.
