Title: Half-cycle pulse ionization of Ba{sup +} Rydberg ions

Abstract

Nearly unipolar, subpicosecond half-cycle pulses (HCPs) have been used to ionize Ba{sup +} ng Rydberg ions. The double ionization probability vs HCP field strength data are compared with analogous single ionization measurements for neutral Ba 6snd Rydberg atoms prepared in the same apparatus. We find that neutral and ionic Rydberg states with the same binding energies follow approximately the same ionization curves. Our findings are in agreement with the predictions of an impulsive ionization model and classical trajectory Monte Carlo simulations.
