摘要	The spin-Hamiltonian parameters (g factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to) A(perpendicular to)) of Ta(4+) ion (which is produced by a self-trapped electron at the Ta(5+) site) in LiTaO(3) crystal are calculated from three theoretical methods, the complete diagonalization (of energy matrix including Zeeman interaction and hyperfine interaction) method (CDM), the first-order perturbation formulas related to (2)T(2) state and the third-order perturbation formulas. From the calculations, it is found that only the calculated results using the CDM show good agreement with the experimental values, but those using the rest two methods do not. The causes are discussed. The defect structure of Ta(4+) defect in LiTaO(3) is also obtained from the calculations. The result is coincident with the expectation based on the electrostatic interaction and electron cloud overlap. (C) 2008 Elsevier B.V.
