✦ Synopsis

The crossed-beam method was used to investigate the charge-transfer reaction of Xe+ ('P,,,) with Xe('S,,). The symmetrically resonant channel producing Xe+ (*P3,*) as well as the endoergic tine-structure transition (producing Xe+ (2P1,2) ) with AJ= -1 were detected. The resonant charge-transfer reaction generating Xe+ ( 2P3,2) is well-described by a standard rectilinear-trajectory theoretical model. Experimental results for both channels are in general accord with accepted theories for ion-atom charge exchange, but the onset threshold of the endoergic channel occurs at much lower energy than that predicted by the linear trajectory model. Evidence of non-zero center-of-mass scattering also observed.
