Abstract : The optical and fluorescent spectra of trivalent Pu-239 in LaCl3 and La(C2H5SO4)3 . 9H2O were investigated together with the paramagnetic resonance absorption of Pu-239 in LaCl3 at 3 cm wavelengths and 4.2K. The optical spectra were taken at 77, 20 and 4.2K on a grating spectrograph. The over-all splitting of the levels as well as the line widths are about the same as those observed in the corresponding salts of Sm(3+) (4F(5)). The magnetic quantum numbers of the 3 crystal field components, the observed energies, and the experimentally determined crystal field matrix elements for the 2 salts are presented. The matrix elements of the concentrated Sm salts are also presented for comparison. Two Pu(3+) doped LaCl3 samples were further investigated by the paramagnetic resonance absorption technique.
