MAGNETIC FIELDS AND NUCLEAR MAGNETIC MOMENTS. Final Report
Technical Report
·
OSTI ID:4050648
Hyperfine interactions and nuclear magnetic moments of short-lived excited states were determined for the rare earth ion in polycrystalline samples of various rare earth iron garnets. The experiments were carried out as a function of temperature to 1000 deg C, the perturbation of the angular correlation due to the hyperfine interaction in the intermediate state of a gamma - gamma cascade following beta decay or K capture processes. Investigations were made of the 1415to 122-kev gamma - gamma angular correlation in Sm/sup 152/, the 1100- to 120-kev gamma - gamma correlation in Gd/sup 154/, and the 879- and 962- to 87-kev gamma - gamma correlation in Dy/ sup 160/. In each case the intermediate state was the 2+ rotational state with a lifetime of the order of 10/sup -9/ sec. The electron spin relaxation times were also determined and their effects on the angular correlation investigated. (M.C.G.)
