Molecular fragmentation in collisions of Multiply Charged Ion with diatomic molecule at energies below 1 keV/u

Abstract

To clarify collision dynamics of the molecular fragmentation involving the charge-asymmetry effects in collisions of slow Multiply Charged Ions (MCIs) with molecules, we have measured the recoil momentum of non-dissociated molecular ions and the branching ratio of molecular fragmentation for single- and multiple-electron capture collisions of MCIs with the diatomic molecule at collision energies below 1 keV/u. The experimental energy dependence of the recoil momentum of molecular ions was in good agreement with the theoretical dependence obtained using the polarization potential at energies below 100 eV/u. The detailed discussions involving experimental results for branching ratio will be presented at the conference.
