Експериментальна установка для дослідження електронних спектрів атомів лужноземельних металів

For research on high-temperature alkali-earth vapor atoms on an experimental equipment "Electronic Spectrometer" developed a new atomic beam source design, which is designed for the evaporation temperature to 700oC. Conducted the first test measurements of electronic spectra of barium atoms in the collision energy range 15-110 eV, energy resolution 0,05-0,08eV and FWHM primary electron beam 0,25-0,3 eV. Carried spectroscopic identification of the lines observed in the spectra of scattered and ejected electrons. Keywords: atomic beam, autoionization, electron, ejected electrons, the electronic spectra.
