摘要：

The influence of Coulomb and spin-orbit interactions on one-photon transitions within the 4f(3) configuration of Nd3+ in YAG is taken into account by a ''direct'' calculation, which explicitly evaluates the eigenstates of 4f(3) and 4f(2)5d. The interconfigurational crystal-field parameters are fitted to the experimental data and the traditional one-electron intensity parameters are retained to account for non-crystal-field mechanisms. A small but significant improvement in the fit is obtained.
