Abstract: | By applying the energy matrix elements,including coulomb interaction and spin orbit coupling,of the strong field coupling scheme for d 2(d 8) electron configuration in trigonal crystal field and adopting the method of complete diagonalization,we calculate the optical spectra and the EPR spectrum of Ni 2+ :LiNbO 3 with C 3V symmetry.The results agree well with the values measured experimentally. |
