Kinematically complete charge exchange experiment in the Cs++Rb collision system using a MOT target - art. no. 123203

Charge exchange is examined with unprecedented precision using the newly de veloped magnetooptical trap-target recoil ion momentum spectroscopy (MOTRIM S) technique. Initial and final state selective, charge exchange cross sect ions are obtained for 6 keV Cs+ colliding with rubidium in 5s and 5p states . For each charge transfer channel, cross sections differential in scatteri ng angle are measured. These data are used to overturn previous long-standi ng conjecture as to the origin of oscillations seen in total charge exchang e cross section measurements, and compare well with an enhanced Demkov mode l calculation.
