The magnitude and temperature dependence of the quadrupole interaction at the /sup 111/Cd site in orthorhombic ..cap alpha..-uranium was investigated between 293 and 17 K. The parent activity /sup 111/In was implanted into uranium metal with an energy of 80 keV and the ..gamma..-..gamma.. TDPAC technique, applied to the 245 keV state in /sup 111/Cd, was used to measure the quadrupole interaction frequency. The derived electric field gradient for Cd in uranium was found to be highly asymmetric (eta = 1) and led to a quadrupole interaction frequency of /sub Q/ = 7.10(7) MHz at 293 K. The temperature dependence of the quadrupole interaction is very strong, /sub Q/ increases to 14.3(2) MHz at 17 K and shows a linear dependence on the temperature. 10 refs., 2 figs.
