Abstract

We provide a new spectroscopic criterion for the observation of the insulator-metal transition in a two-component system, which is based on the disappearance of Wannier exciton states in the metallic region. This effect has been observed in the vacuum-ultraviolet spectra of mercury/xenon mixtures deposited at 10-30°K, where the Xe Wannier states are abruptly washed out at (55±5)% of Hg.
