STATE-SELECTIVE ELECTRON-CAPTURE IN THE INTERACTIONS OF PARTIALLY STRIPPED IONS OF BERYLLIUM AND BORON WITH ATOMIC-HYDROGEN IN THE GROUND-STATE

The Coulomb-Born approximation has been employed to study charge trans fer cross sections in the case of collisions of Beq+ (q = 1-3) and Bq (q = 1-4) with atomic hydrogen in its ground state, respectively, wit hin the energy range of 25-200 keV amu(-1). The interaction of the act ive electron with the incoming projectile ion has been approximated by a model potential. Cross sections for capture into different sub-shel ls have been given in tabular form. Computed total capture cross secti ons compare favourably with existing available results.
