Abstract
Excitation of selenium by slow electrons (2–50 eV) was studied experimentally. Emission spectra were measured in the 200–590 nm region at electron energies of 20, 30, and 50 eV. The spectra show molecular emission bands in the 300–560 nm region and Se atom lines. It was found that, at a temperature of 440 ± 5 K, selenium vapor contains polyatomic molecules, as well as a large amount of diatomic Se2 molecules. The atomic emission lines are due to dissociative excitation of Se2.
