OSTI ID:4752156
The hyperfine interactions of the 2+ rotational level of Dy/sup 160/ at 87 kev in dysprosium -iron garnet were measured at 94 deg K using the technique of Mossbauer absorption. A comparison with previous similar measurements in Dy/ sup 161/ together with the knowledge of the g factor of the Dy/sup 161/ ground state from spin resonance experiments gave a value of 0.48 plus or minus 0.07 for the g factor of the 2+ rotational level of Dy/sup 160/. The sign of the spectroscopic quadrupole moment of this state was negative. The ratio of quadrupole moments Q sub 160 (2+)/Q sub 161 (ground state) was -0.77 plus or minus 0.25. Comparing a model dependent estimate of Q sub 160(2+) with a value of Q obtained from the experimental results, a value of about 0.2 is obtained for the Sternheimer shielding factor. (auth)
