Experimental studies of resonant charge transfer from Rydberg states by highly-charged ions

Two recent experiments studying charge transfer between slow multiply charg ed ions and a dense CW Rydberg target are described, one studying the total charge transfer cross section and the other the details of the energy tran sfer. Together, these experiments provide a detailed picture of many import ant aspects of the charge transfer process, and confirm theoretical predict ions obtained with Classical Trajectory Monte Carlo methods.
