✦ Synopsis

The binding energies of the Wannier exciton-ionized donor complex are calculated for direct and indirect excitons in crystals of thallium halides. Several alternative forms recently proposed in the literature for the electronhole effective interaction potential are considered. In all cases the complex is found to be unstable, and its binding energy very close to the bare exciton binding energy. The possible relation of these results to the available experimental data is pointed out.

The effect of large electric fields on the photoconductivity spectra of liquid xenon is reported. The photoconductivity threshold shifts to lower photon energies with increasing applied electric field. From its magnitude and functional dependence, it is concluded that the shift is due to the field i
