    "abstract": "We report new accurate mesasurements of the mobility of excess electrons in\nhigh density Helium gas in extended ranges of temperature $[(26\\leq T\\leq 77) K\n]$ and density $[ (0.05\\leq N\\leq 12.0) {atoms} \\cdot {nm}^{-3}]$ to ascertain\nthe effect of temperature on the formation and dynamics of localized electron\nstates. The main result of the experiment is that the formation of localized\nstates essentially depends on the relative balance of fluid dilation energy,\nrepulsive electron-atom interaction energy, and thermal energy. As a\nconsequence, the onset of localization depends on the medium disorder through\ngas temperature and density. It appears that the transition from delocalized to\nlocalized states shifts to larger densities as the temperature is increased.\nThis behavior can be understood in terms of a simple model of electron\nself-trapping in a spherically symmetric square well.",
