Abstract

A pulsed tunable UV laser was used to photodissociate LiI. Lithium atoms were detected by three-step resonance ionization spectroscopy (RIS) to obtain absolute dissociation cross sections from 270 to 312 nm. A comparison of the present cross sections at T = 140°C with absorption data at higher temperature (T = 745°O shows that dissociation is a dominant channel following photon absorption. We infer that the repulsive upper state of the corresponding transition crosses the ionic ground-state potential curve.
