Abstract
Isotope-selective laser excitation has been used to study excitation exchange in collisions of helium Rydberg atoms with ground-state helium; this process is dominated by the interaction of the ionic core with the neutral atom and proceeds at the charge-exchange rate, the excited electron remaining a spectator.Keywords
