Abstract
New ionic states of alkali halide molecules, which are isoelectronic to the neutral rare gas halide molecules, have been generated by direct photoionization using the soft x-ray flux from a laser-produced plasma. The fluorescence emission of three ionic excimer transitions has been observed at 185 nm for CsF, 208 nm for CsCl, and 130 nm for RbF. The emission wavelengths are in good agreement with those calculated using Rittner-type potentials. The vibrational structure in the emission spectrum of CsF has been calculated and excellent agreement with the experiment is found. A model for photoionization of these molecules has revealed that the vibrational population of the bound photoionized state is Boltzmann distributed if the neutral ground state has a thermal vibrational distribution.
