英文摘要	The spin-Hamiltonian parameters, g factors and hyperfine structure constants, for the tetragonal and cubic Yb3+ centers in AgCl crystal are calculated from the complete diagonalization (of energy matrix) method. The calculations are based on the defect models that the tetragonal Yb3+ center is formed by the substitutional Yb3+ associated with two nearest Ag+ vacancy (V-Ag) along < 001 > and < 001 > axes (i.e.. C-4 axis) owing to charge compensation and in cubic Yb3+ center the two compensators V-Ag are remote. From the calculations, the spin-Hamiltonian parameters of both Yb3+ centers in AgCl are explained reasonably, the signs of hyperfine structure constants A(i)(Yb-171(3+)) and A(i)(Yb-173(3+)) are suggested, the above defect models of both Yb3+ centers are confirmed and their defect structures are determined.
