INTERMEDIATE STATE REORIENTATION OF COBALT-57 NUCLEI ALIGNED IN CERIUM ZINC NITRATE

Abstract

Radiation pattern and linear polarization of gamma rays from decay of Co-57 aligned at low temperatures by Bleaney's method in the Y-sites of cerium zinc nitrate were studied for evidence of intermediate state reorientation in this crystal. Influence of spin-spin interactions should be negligible on theoretical grounds. Experimental results are expressed in terms of the mixing ratio delta for the 123 kev M1 E2 gamma transition and of an attenuation coefficient Q sub k (delta 0.148 = 0.010, Q2 0.81 = 0.10 at 1/T* 157.) Comparisons are made with Steen berg's theory of intermediate state reorientation by static, isotropic hfs coupling in the hard core limit, and with results of another nucle alignment experiment involving the same isotope.
