Abstract
A new experiment shows that in dense, cold helium gas an excess electron can occupy either a distinct group of highly mobile states or another group of relatively immobile, presumably localized states. The rapid decrease in average mobility with increasing gas density observed in previous experiments arises primarily from an exponential increase in the lifetime of the electron in the localized states.Keywords
