Energy Level Structure and Transition Probabilities in the Spectra of the Trivalent Lanthanides in LaF₃

One of 1,237 reports in the series: Argonne National Laboratory Reports available on this site.

Description

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.
