Significant new evidence is reported for resonant transfer and excitation in ion-atom collisions. This process, which is analogous to dielectronic recombination, occurs when a target electron is captured simultaneously with the excitation of the projectile followed by photon emission. It was investigated for collisions of 100--360-MeV sub20Casup16+,17+,18+ and 180--460-MeV sub23Vsup19+,20+,21+ with He by measurement of the cross section for projectile K x rays coincident with single electron capture. For both collision systems, strong resonant behavior with structure is observed in the coincidence cross section in agreement with theoretical calculations.
