Abstract
Electron correlation has been studied in the singly ionized 5p(-1), 5s(-1) and 4d(-1) states and the double ionized (5s, 5p, valence)(-2) states of Ba by carrying out extensive configuration interaction Hartree-Fock calculati ons including the mixing of configurations with outermost valence electrons (nl = 6s, 5d, 6p, 4f,...). The results of calculations have been compared with existing experimental photoelectron, ion-yield, electron-ion coinciden ce, and Auger electron spectra.
