Abstract

Nonrelativistic, relativistic, quantum electrodynamic, and finite nuclear mass corrections to the energy levels are obtained for the nS1/2,n=3,,9 states of the lithium atom. Computational approach is based on the explicitly correlated Hylleraas functions with the analytic integration and recursion relations. Theoretical predictions for the ionization potential of nS1/2 states and transition energies nS1/22S1/2 are compared to known experimental values for Li6,7 isotopes.
