摘要	The spin-Hamiltonian parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants (143)A(parallel to), (143)A(perpendicular to), (145)A(parallel to), (145)A(perpendicular to)) for Nd(3+) ion at the tetragonal Zr(4+) site of ZrSiO(4) crystal are calculated from a diagonalization (of energy matrix) method. In the method, the Zeeman and hyperfine interaction terms are added to the conventional Hamiltonian and a 52 x 52 energy matrix is obtained for 43 ions in tetragonal symmetry on the basis of the ground multiplet (4)I(9/2) and the first to third excited multiplets (4)I(11/2), (4)I(13/2) and (4)I(15/2). The calculated results are in reasonable agreement with the observed values. The defect structure of Nd(3+) center is determined and the signs of hyperfine constants (143)A(i) (i = parallel to or perpendicular to) and (145)A(i) are suggested from the calculations. The results are discussed. (C) 2009 Elsevier B.V. All rights reserved.
