摘要	The optical spectra and EPR parameters (g factors g(\\), g(perpendicular to) and hyperfine structure parameters A(\\), A(perpendicular to) of Sm-147 and Sm-149) of Sm3+ in CaWO4 crystal are calculated from the second-order perturbation formulas of EPR parameters for a 4f(5) ion in tetragonal symmetry. In these formulas, the J-mixing among the H-6(J)(J = 5/2, 7/2 and 9/2) states via crystal-field interactions, the mixtures among the states with the same J value via spin-orbit coupling interaction and the interactions between the lowest Kramers doublet Gamma(gamma) and the same irreducible representations in the other 11 Kramers doublets Gamma(x) via the crystal-field and orbital angular momentum (or hyperfine structure) are considered. The theoretical results agree reasonably with the observed values.
