Artykuł
High-resolution absorption spectra of thin films of UCl3 and UBr3 have been measured at 4.2 K in the 4000–30 000 cm−1 range. The determined crystal-field lines were used in a computational analysis employing free-ion operators, one-electron crystal-field operators as well as two-particle correlation crystal-field operators. The performed analysis enabled the determination of the Hamiltonian parameters and an unambiguous assignment of 57 and 46 crystal-field levels with a mean error of 31 cm−1 for UCl3 and UBr3, respectively.
