摘要：

Partial cross sections and angular-distribution asymmetry parameters of diagram and satellite lines associated with Li ls photoionization were measured using synchrotron-radiation excitation. Special emphasis was given to a high-resolution study of the 1P and 3P conjugate shakeup satellite lines testing qualitative predictions of the conjugate shakeup model: increasing sigma and decreasing beta values towards threshold, both being verified. Comparison with recent relaxed Hartree-Fock calculations shows good agreement for the 1P satellite, but also demonstrates that the present theory does not seem to be able to describe the cross-section behavior of the 3P satellite correctly.
