Kinematically Complete Charge Transfer Cross Section Measurements for Energetically Degenerate Channels
Abstract
Cold Target Recoil Ion Momentum Spectroscopy (COLTRIMS) has become a powerful tool to study collisions. However, traditional methods for cooling the target, namely supersonic expansion is not suitable for targets with optically active electrons since these species generally form clusters or dimers upon expansion. Thus, the study of laser excited targets is problematic. Furthermore, even after supersonic expansion, initial target temperature still limits recoil ion momentum resolution. With recent advancement in recoil ion momentum spectroscopy, these measurements are now possible through MOTRIMS (Magneto Optical Trap Recoil Ion Momentum Spectroscopy). This technique allows 'in situ' measurements of target excited state fraction and kinematically complete relative cross sections even for many systems having energetically degenerate channels. Results for 7 keV Li+ + Rb will be presented.
