SINGLE ELECTRON CAPTURE AND TRANSFER IONIZATION IN SLOW KR13+/BF3 COLLISIONS

We investigated the single electron capture and the transfer ionization in the system Kr13+/BF3 at 26.8 keV. The following results are obtained for Kr12+ ions scattered at 0°: 60% of the Kr12+ ions result from pure single electron capture and 40% result from transfer ionisation. The BF3+ molecular ion dissociates with large probability into BF2+ + F or BF+ +2F. The mean kinetic energies of the molecular fragments are determined and discussed with respect to the mechanism of the fragmentation process.
