Abstract: | The nonrelativistic energies for lithium isoelectronic sequence
1s2ng and 1s2nh (n=5, 6, 7, and 8) states from Z=3 to 8
are calculated by using a full core plus correlation (FCPC)
method with multiconfiguration interaction wave functions.
Relativistic and mass-polarization effects on the energy
are evaluated as the first-order perturbation theory.
Our predicted excitation energies are compared with previous
experimental results in the literature. |
