Description
Polarized absorption spectra covering the wavelength range 5600 to 25 000 A are reported for U3+(5f 3) doped into single crystal LaCl3. Spectra were recorded at liquid helium, liquid nitrogen, and at room temperatures. Temperature-dependent polarized spectra help establish many crystalline electric-field (CEF) split J levels not directly excited from the ground state due to selection rules for C/sub 3h/ symmetry. Analysis of the data confirms the earlier (1959) assignments made by S. P. Cook at The Johns Hopkins University to the ground state manifold Stark levels. For 4I/sub 9/2/, the ground state manifold, we find: μ ( +- 5/2) =0, μ ( +- 1/2) =210, μ ( +- 3/2) =241, μ ( +- 5/2) =440, and μ ( +- 3/2) =458 all in energy units of cm-1. Uncertainty in establishing these levels is within several wave numbers and involves over 150 temperature-dependent transitions
