摘要

The complete energy matrix for a 4f~(13) ion in cubic crystals and under an external magnetic field is established by means of the irreducible tensor operator and/or equivalent operator methods. By diagonalizing the energy matrix, four optical spectrum band positions and three spin-Hamiltonian parameters [g factor and hyperfine structure constants A(~(171)Yb~(3+)) and A(~(173)Yb~(3+))] for Yb~(3+) in InP semiconductor are calculated together. The calculated results are in good agreement with the experimental values. The signs of hyperfine structure constants A(~(171)Yb~(3+)) and A(~(173)Yb~(3+)) are determined from the calculations. The results are discussed.
