Abstract
An EPR spectrum with orthorhombic symmetry of U3+ in SrF2 has been investigated. The principal axes and characteristic values of the g-tensor ellipsoid were determined. Twelve equivalent, yet distinguishable, spectra were resolved. The 12X axes lie in {110} planes and are 15° from <110> directions. The Y axes lie in the same {110} planes 90° from the corresponding X axes (i.e., ± 15° from <100> directions). The 12Z axes were found to be in the <110> directions perpendicular to the {110} plane which contains the corresponding X and Y axes. These principal axes were determined to within ± 0.5°. The principal g values are gx=1.3276±0.0005, gy=2.88±0.01, and gz=3.183±0.002. A rotating sample holder which facilitated this investigation will be discussed briefly.
