Abstract:

The hyperfine interactions of the 2 rotational level of Dy-160 at 87 kev in dysprosium iron garnet were measured at 94 K using the technique of Mossbauer absorption. A comparison with previous similar measurements in Dy-161 together with the knowledge of the g factor of the Dy-161 ground state from spin resonance experiments gave a value of 0.48 0.07 for the g factor of the 2 rotational level of Dy-160. The sign of the spectroscopic quadrupole moment of this state was negative. The ratio of quadrupole moments Q sub 160 2Q sub 161 ground state was -0.77 0.25. Comparing a model dependent estimate of Q sub 1602 with a value of Q obtained from the experimental results, a value of about 0.2 is obtained for the Sternheimer shielding factor. Author
