【 摘 要 】

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 5p55d6s2and 5p55d26s configurations were determined.
