Electron stimulated oxidation of thallium
With use of electron Auger spectroscopy and spectroscopy of characteristic losses of energy electrons, the kinetic of oxygen adsorptions on thallium has been investigated for two cases ─ at a continuous electron irradiation (100 ─ 1000 eV) and without it depending on an exposition in the environment of oxygen at pressure of oxygen 10 -6 Torr and a room temperature. The maximum exposition in oxygen 10 -6 Torr has made 5000 L and at atmospheric pressure - 5 minutes. The exposition of thallium in the environment of oxygen in few hundred L with a simultaneous irradiation slow electrons led to increase in concentration of oxygen at surfaces and displacement of peak of thallium on 1.0 eV.
