Abstract
The absorption spectrum of Nd3Ga5O12 has been analysed at 4, 77 and 300K between 5000 and 35000 cm-1 for which an energy level scheme of 104 Stark levels is derived. Both free-ion (12 parameters) as well as crystal-field parameters (9 for the D2 symmetry of the Nd point site) of an effective operator Hamiltonian were fitted to the data and close correlation between experimental and simulated level energies was obtained with a mean quadratic deviation of 18 cm-1 on the 364 kets basis in the 4f3 configuration.Keywords
