Distinct temp. effects could be obsd. in the threshold regions of photoionization efficiency (PIE) measurements of Na clusters. Simulations of the PIE thresholds at various temps. were carried out with a simple, semiclassical model. Fitting the simulations to the exptl. data allows to correct ionization potential assignments for thermal effects and est. internal temps. of polyat. N clusters. [on SciFinder (R)]
