Hartree-Fock and Configuration Interaction Calculations of Hyperfine Constants in Quartet States of Three-electron Atoms

The hyperfine structure constants in the lowest 4 P o and 4 P e states of the isoelectronic sequence Li- F 6+ have been calculated from Hartree-Fock and accurate configuration interaction (CI) wavefunctions, in good agreement with available experimental results for Li. In addition, Hartree-Fock calculations of energies and hfs constants for several higher 4 S , 4 P o , 4 D and 4 D o states of Li are reported.
