Title: Energy level structure and transition probabilities in the spectra of the trivalent lanthanides in LaF₃

Two types of correlations with experimental results are reported. For even-f-electron systems, a center of gravity was computed based on the energies of the observed states, and calculated optimized sets of atomic energy level parameters. For odd-electron systems complete crystal field calculations were performed in which parameters of both the atomic and crystal-field parts of the interaction were adjusted to experimental data. The result is a set of eigenvectors for all the ionic states in each configuration. Spectroscopic results for all lanthanides doped into LaF₃ (In³⁺:LaF₃) except Pm³⁺ and Eu³⁺ are reported. 89 references, 29 tables.
