Abstract
The relativistic energies, the oscillator strength, and the lifetimes of high-lying core-excited states 1s2s2pnp 5P (n=2–5) and 1s2p2mp 5So (m=2–5) of Li- ion are calculated with the saddle-point variational method and restricted variation method. The fine structure and the hyperfine structure of the core-excited states for this system are also explored. The results are compared with other theoretical and experimental data in the literature.
