Electronic spectra of autoionization states of barium, observed in electron-atom collisions
Aleksakhin I.S. , Borovik A.S. , Zapesochnyi I.P.
Electron spectroscopy using the technique of intersecting electron and atom beams was used to study, for the first time, the spectra of electrons emitted by barium atoms. It is established that the discrete electron groups observed in the spectrum, with energies 6-16 eV, correspond to the decay of the excited autoionization states of Ba and Ba+.
