Optical properties of tetravalent uranium in the solid state

PDF Version Also Available for Download.

Description

The optical spectra are fit to the parameters of a phenomenological Hamiltonian from which a calculated spectrum is obtained. The goodness of fit is determined by the value of sigma (cm/sup -1/), the rms deviation. The sigma and crystal field are tabulated for U/sup 4 +/ in various host crystals, Pr/sup 3 +/ or Nd/sup 3 +/ in various crystals, and the free ion U/sup 4 +/. The rms deviation sigma for the U/sup 4 +/ compounds is much worse on the average than for the Pr/Nd examples. There appears to be a correlation between a poor fit and a ... continued below

There appears to be a correlation between a poor fit and a large sigma, and a large crystal field. 28 refs., 1 tab. (DLC)
