Partial cross-sections for photoionization with excitation of Li{sup +} leaving the remaining bound electron in the 1s, 2s, 2p, 3s, 3p, and 3d states and total cross-sections for double photoionization have been calculated employing the time-dependent close-coupling method. The calculations include both the ground state 1s{sup 2} {sup 1}S and the two lowest metastable excited states 1s2s {sup 1,3}S. Photon energies below and up to about 200 eV above the respective thresholds for double ionization are considered. Comparisons are drawn mainly with convergent close-coupling results [A. S. Kheifets and I. Bray, Phys. Rev. A 58, 4501 (1998)] and B-spline based R-matrix results [H. W. van der Hart and L. Feng, J. Phys. B 34, L601 (2001)].
