【 摘 要 】

Large scale configuration interaction calculations of energy levels, autoionization probabilities and electron-impact excitation cross sections of the autoionizing states 4p5nln'l' (nl = 5s, 4d, 4f,n'l'=4d, 5s, 5p, 5d, 5f, 5g, 6s, 6p, 6d, 7s, 7p) of Rb up to 19.6 eV were performed for the first time. The relativistic effects were taken into account in the Dirac-Fock-Slater approximation. The calculated data were used for the novel classification of the lines in an experimental ejected-electron spectrum.
