英文摘要	The six optical band positions and six spin-Hamiltonian parameters [g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to)(Yb-171(3+)), A(perpendicular to)(Yb-171(3+)), A(parallel to)(Yb-173(3+)), A(perpendicular to)(Yb-173(3+))] for Yb3+ ion at the tetragonal Y3+ site of KY3F10 crystal are calculated from a diagonalization (of energy matrix) method. In the method, the Hamiltonian of energy matrix contains the free-ion, crystal-field interaction, Zeeman (or magnetic) interaction and hyperfine interaction terms and so a 14 x 14 complete energy matrix for 4f(13) ion in tetragonal crystal-field and under an external magnetic field is constructed. Diagonalizing the energy matrix, these optical and EPR spectral data are calculated together and the calculated results are in reasonable agreement with the experimental values. The signs of hyperfine structure constants A(parallel to), A(perpendicular to) for the isotopes Yb-171(3+) and Yb-173(3+) in KY3F10 are suggested. The results are discussed. (C) 2011 Elsevier B.V.
