Spectroscopic Classification Of The 5p(5)N(1)L(1)N(2)L(2)N(3)L(3) Autoionizing States In Ba Atoms

The ejected-electron spectra of Ba atoms were measured in an electron impact energy range 15-100 eV. By comparative analysis of experimental and calculated data on excitation dynamics and excitation thresholds of lines the complete spectroscopic classification and decay channels for autoionizing states in 5p(5)5d6s(2) and 5p(5)5d(2)6s configurations were determined.
