Abstract

We report the observation of exciton-induced photoemission resulting from electronic energy transfer from "free" exciton levels to impurity states in solid Xe and Kr. A diffusion length of l075 for Wannier excitons in solid Xe was deduced, corresponding to a diffusion coefficient of D=0.5 cm2 sec-1. The energy of the bottom of the conduction band is V0=-0.46±0.1 eV for Xe and V0=-0.23±0.1 eV for Kr.
