We report on the first {ital Q}-value measurements in charge-transfer collisions using recoil longitudinal momentum spectroscopy. This method is not limited to relatively low beam energies and is easily adaptable to captures involving any number of transferred electrons. A very monoenergetic beam is not necessary. For a 50-keV Ar{sup 15+} on Ar collision system, {ital Q} values coresponding to single through quintuple electron capture were measured and found to be in good agreement with the predictions of the molecular classical overbarrier model.
