摘要：

Binary and ternary potassium, rubidium and caesium glasses were irradiated by an electron beam with energy varying from 10 to 50 keV. Alkali ion X-ray decays were recorded and afterward incubation periods were determined. The incubation period versus electron energy curves revealed thresholds, which are typical for each alkali species. The threshold ratios are proportional to the mass of the alkali species, consistent with the suggested elastic scattering assisted hopping mechanism.
