    The electronic paramagnetic resonance g factors g(parallel to), g(perpendicular to) of Dy3+ centers and the hyperfine structure constants A(parallel to) and A(perpendicular to) of Dy-161(3+) and Dy-163(3+) isotopes in ZrSiO4 crystal are theoretically studied from the perturbation formulas of the spin Hamiltonian parameters for a 4f(9) ion in tetragonal symmetry. In these formulas, the contributions to g factors due to the J-mixing among the ground H-6(15/2), the first excited H-6(13/2) and second excited H-6(11/2) states via crystal-field interaction, the admixtures among the states with the same J value via spin-orbit coupling interaction and the interactions between the lowest Kramers doublet Gamma gamma and other 20 Kramers doublets Gamma(X) within the states H-6(J) (J = 15/2, 13/2 and 11/2) via crystal-field and orbital angular momentum interactions are considered. The calculated EPR parameters show reasonable agreement with the observed values. The results are discussed.
