✦ Synopsis

The crossed-beam method was used to investigate the charge-transfer reaction of IW ( 2P,,2) with Kr( 'S,), using a nearly pure Kr+ ( *Pyz ) ion beam. The resonant charge-transfer reaction is well described by a standard theoretical rectilinear-trajectory model. The endoergic fine-structure transition with AJ= 1 was also detected. This product is scattered at a definite angle, suggesting a short-range interaction which selects a particular impact parameter. Both channels are in general accord with accepted theories for ion/atom charge exchange, but the energy range at which the endothermic channel is observed is much lower than predicted.
