Electronic excitations of pure and doped rare-gas fluids: Theory and experiment.

Abstract

It is shown that a mean-spherical model with no adjustable parameters developed by Chandler, Schweizer, and Wolynes [Phys. Rev. Lett. 49, 1100 (1982)] is in rough agreement with the experimentally observed shifts of photoconductivity thresholds in pure and doped rare gases. This holds for a wide density range. However, the theory always yields a red shift for discrete absorption lines and bands, while in the experiments blue shifts are dominant, essentially as a result of correlation effects.
