摘要：

The evaporation rates and saturation vapor pressures of cadmium sulfide and pure metallic cadmium are measured in the temperature ranges 585-950 K and 350-535 K, respectively, using laser resonance multistep photoionization. It is shown that CdS thermally dissociates into Cd atoms and S-2 molecules. The study is carried out in the framework of a scheme proposed earlier for photoionization of cadmium atoms. The measured minimum vapor pressure of pure cadmium is 10(-11) Torr. (C) 2003 MAIK "Nauka/Interperiodica".
