Charge transfer collisions between slow ions and Rydberg atoms have been studied for ion charges q=1{endash}4 , using resonant laser excitation to detect specific energy states of the collision products. The data collected show a clear resonance in the capture cross section to a particular energy state as the binding energy of the Rydberg target is varied. The resonance position differs significantly from the predictions of the classical overbarrier model, and its width becomes very small (0.025thinspthinspeV) at the lowest velocities studied. {copyright} {ital 1998} {ital The American Physical Society}
