Charge transfer collisions between slow ions of charge q=1-11 and
Rydberg states of rubidium with principal quantum number n=7-26, have
been studied using selective laser excitation to determine both the
initial Rydberg binding energy and the final binding energy of the
transferred electron.  The result is a comprehensive and precise
determination of both the position and the width of the capture
resonance.
