We have examined resonant multiphoton ionization (REMPI) in HI using a tunable nanosecond dye laser. The parent ion, HI+, is produced by a 1+1 REMPI process with the excitation wavelength resonant with the first UV continuum. of HI. Sharp features in the wavelength-resolved spectrum of HI+ are recorded and are assigned to two-photon transitions to autoionizing Rydberg states with a finite lifetime. Differences in the two-photon spectra compared to data obtained by single-photon VUV photoionization are noted. A simple kinetic analysis of the data is employed to illuminate the mechanism of ionization and to explain the observed laser flux dependence. of the parent ion signal.
