Seven crystal field energy levels (obtained from the optical spectra) and three g factors g(x), g(y) and gz (obtained from electron paramagnetic resonance (EPR) spectra) for Ce(3+) ion in Y(3)Ga(5)O(12) crystal are calculated together by diagonalizing a complete energy matrix. The Hamiltonian of this energy matrix includes all the interactions for 4f(1) ion Ce(3+) in rhombic crystal field and under an external magnetic field, and so the optical and EPR data can be studied in a unified way. The calculated crystal field energy levels are in better agreement with the experimental values than the calculated values in the previous paper, and the g factors (which have not been calculated previously) are explained reasonably. The results are discussed. (C) 2011 Elsevier B.V. All rights reserved.
