Abstract
Calculations of the electronic structure of the F centre in KMgF3 are reported and their results compared with experiment. The hyperfine interaction of the ground state with the nearest F- ion is predicted to be 70 G, in good agreement with the experimental result of 60 G. The energy for optical absorption to the Eu excited state is given by a point-ion calculation as 4.4 eV, compared with the observed 4.6 eV. The predicted spin-orbit splitting of the excited state is 57 cm-1, close to the experimental value of 60 cm-1.Keywords
