Excitation and ionization processes of sulfur, selenium, and tellurium vapors by a low-energy (1-50 eV) electron impact have been investigated. The emission spectra are studied in the wavelength range 200-590 nm. The optical excitation functions for the most intense atomic and ionic spectral lines, as well as for molecular bands and emissions, are measured. The energy dependences of the total cross sections for the formation of positive and negative sulfur and selenium ions by the electrondoi:10.15407/ujpe60.03.0217 fatcat:aepnah5r2zcuvoubzgw5hrxrue
