Abstract
A newly developed saddlepoint multichannel Kmatrix method is used to study the photoionization of lithium from 1s(2)2s and 1s(2)2p for photon energies near the 2p2p2p P2(o) and 2s2p2p L2(e) (L = 0,1,2) resonances. Highlyaccurate initial and targetstate wave functions are used and up to 17 open channels are included in the calculation. The calculated partial and total photoionization cross sections are compared with the available theoretical and experimental data. The partial cross sections obtained in this work suggests that for Li 1s(2)2p and 1s(2)2p initial states, the Is electron with spin antiparallel to that of the 2s (or 2p) electron is the one most likely to be ejected in the photoionization process. The elastic and inelasticelectronion scattering cross sections are also calculated. The relative magnitude of the calculated collision strength is compared with the Auger branching ratios for these resonances.
