L-changing Collisions in Cold Rydberg Gases


Using spectroscopic methods and time-resolved electron counting, it is found that clouds of cold Rydberg atoms can emit electrons over a surprisingly long time scale. Our observations are explained by l-mixing collisions between Rydberg atoms and slow electrons. The thereby created high-angular-momentum Rydberg atoms thermally ionize slowly and with large… (More)
