Large-scale multiconfiguration Dirac-Fock calculations of the hyperfine-structure constants of the 2s 2S1/2, 2p 2P1/2, and 2p 2P3/2 states of lithium.

The hyperfine constants for the ground and two lowest excited states of lithium are calculated in a multiconfiguration Dirac-Fock model. Convergence of the calculated magnetic dipole and electric quadrupole constants is studied as the active set of orbitals is systematically increased. The final results are compared with experimental data and theoretical values obtained from other methods. \textcopyright{} 1996 The American Physical Society.
