摘要：

The photoionization of lithium to energies between the Li+ 1s2s(3)S and 1s2p(1)P thresholds is studied with accurate ground and target state wave functions. Saddle-point full-core plus correlation wave functions are used for the closed channel. The result agrees with recent photoion measurements. Thirty nine resonances are found in the observed spectra and the predicted sharp peaks agree with experiment to meV levels. The predicted line profile agrees closely with experiment. Several earlier identifications are reassigned. Strong mixing of different resonance series is also found in a few instances.
