Abstract The nonrelativistic energies of the core-excited ls2snp ⁴P (n =2, 3, 4, 5) states for the lithium isoelectronic sequence from Be II to O VI are calculated with a full core plus correlation method using multiconfiguration interaction wavefunctions. The relativistic and mass-polarization effects on the energy are evaluated as the first order perturbation theory. Our predicted energies are lower than other theoretical results. They show that this full core plus correlation method is useful for the core-excited systems.
