Fragmentation of H2^2+ ions following double electron capture in slow Xe23+ and O5+ + H2 collisions

Résumé

The energy distributions of H+ fragments produced in 345 keV Xe23+ + H2 and 75 keV O5+ + H2 collisions have been investigated experimentally as a function of the detection angle. For both systems, the experiment shows strong deviations from the molecular Coulomb explosion. Two- and three-body model calculations have also been performed to understand the energy spectra. In the collisions involving the heaviest projectile Xe23+ , the two-body calculations reproduce the experimental data satisfactorily, indicating that the recoil energy transferred to the target plays an important role in the fragment-energy distributions. On the other hand, for the system O5+ + H2, the deviations between calculations and experiment suggest that the interaction between the outgoing projectile and each fragment plays the major role.
