Popis:	The influence of Coulomb and spin-orbit interactions on one-photon transitions within the 4f 3 configuration of Nd 3+ 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.
