Abstract
Calculations of [Formula Presented] electron inner-shell photoionization from the [Formula Presented] Li ground state have been performed using recent developments of the [Formula Presented]-matrix code with a 19-term target representation for incident photon energies up to 130 eV. This photon energy range allows important resonances in the partial cross sections due to [Formula Presented] autoionizing states to be obtained. Theoretical resonant results are compared with recent experimental measurements of Kiernan et al. [J. Phys. B 29, L181 (1996)] in the [Formula Presented] threshold region. Partial cross sections, branching ratios, and asymmetry parameters are also compared outside the resonant energy range with previous theoretical results of Lisini, Burke, and Hibbert [J. Phys. B 23, 3767 (1990)], who used the [Formula Presented]-matrix code with an 11-term target representation, as well as the corresponding experimental results of Ferret et al. [Phys. Rev. A 36, 3172 (1987)], Langer et al. [Phys. Rev. A 43, 1652 (1991)], and Cubaynes et al. (private communication). © 1998 The American Physical Society.
