ABSORPTION SPECTRUM OF U4(+) IN ZIRCON (ZRSIO4).
Abstract
The electronic energy levels of U4(+) in ZrSiO4 have been obtained from the absorption spectra of oriented single crystals. This host was chosen because of the relatively high summetry of the Zr4(+) site occupied by the U4(+) ion. Spectra were obtained at a number of temperatures between 4 and 300 K. By means of polarization selection rules, electronic energy levels were identified according to their irreducible representations, and the Slater integrals the spin-orbit parameter, and the crystal-field parameters then were determined by a least-square fit. Because of the large crystal field, it was necessary to diagonalize all these interactions within the 5f2 configuration. In all, 30 levels up to 24,000 reciprocal centimeters have been fitted to an average deviation of 110 reciprocal centimeters by adjusting nine parameters.
