Popis:	An extension of previous single-channel calculations is presented for the photoionization cross sections of Li 1s diagram and conjugate shake-up satellite lines. The extension includes the effects of interchannel interaction to first order in the channel-channel interaction matrix. The calculations demonstrate the large role played by continuum configuration interaction in the problem. Interchannel interaction is shown to transfer intensity from the diagram channels into the conjugate shake-up channels. In particular the 1s2p(3P) conjugate shake-up state, which was previously predicted to have no intensity, is now calculated to have an intensity as large as 28% that of the 1s2s(3S) diagram transition. The present results are discussed with reference to current experimental results and contrasted to the previous calculations.
