Recoil momentum of molecular ions in collisions of Ar6++N2 at energies below 300 eV/u

Abstract

To elucidate the collision energy dependence of the recoil momentum of molecular ions after electron transfer, we measure the recoil momentum of non-dissociated molecular ions for single electron capture collisions of Ar6+ with N2 at collision energies from 7.5 to 240 eV/u. The measured collision energy dependence of the recoil momentum is compared with those obtained by a theoretical calculation using a deflection function with polarization potential. We obtain fairly good agreement between the measured and calculated results.
