Abstract

In an atomic beam magnetic resonance experiment the hyperfine interaction constantsA andB of the5 I 8 groundstate of Dy161 and Dy163 were found to be Dy161:A=−(115.8±1)MHz, Dy163:A=(162.9±0.6)MHz,B=(1102±15)MHz,B=(1150±20)MHz.

Using an effective value for 〈r−3〉, the magnetic moments and electric quadrupole moments of the Dy161 and Dy163 nuclei were calculated to be Dy161:μ I=−(0.47±0.09) n.m., Dy163:μ I=(0.66±0.13)n.m.,Q=(2.36±0.4)barns,Q=(2.46±0.4)barns.
