摘要：

Recent optical measurements of a 1.4 eV doublet in diamond have revealed distinct optical polarization features which are associated with a nickel defect. A model for the defect is investigated taking into account the large electronic hybridization that will take place about the metal ion. Relative spectroscopic intensities and estimates of the spin-orbit interaction are considered within the LCAO approximation. Finally, a cluster model calculation is made specifically to investigate the electronic structure of the nickel defect and estimate the LCAO coefficients. From the results, suggestions are made about the possible charge states and lattice locations of nickel in diamond.
