A Z-expansion procedure is used to obtain eigenvalues and eigenfunctions for the 1s22p2Po, 1s2p22P, and 1s2p22D states of the lithium sequence. Expansions in inverse powers of the nuclear charge Z are obtained also for the dipole-matrix elements and oscillator strengths of the 1s22p2Po-1s2p22P and 1s22p2Po-1s2p22D transitions, valid for Z > 3. A separate calculation was performed for lithium. The calculated transition probabilities agree with the Hartree-Fock values of Gabriel for large Z, but there are considerable discrepancies with the experimental data.
