Magnetic moment of the 3/2 +  state in 165Ho

The Larmor precession for the 362 keV state in 165Ho(Iπ = 3/2 + , T1/2 = 1.512 μs) in Dy2O3 with an external magnetic field of 0.3 T was determined to be − 32.3 ± 0.6 MHz by use of the perturbed angular correlation technique, intending to determine the magnetic moment and apply it to the measurement of the hyperfine field at Ho in Fe. The magnetic moment for this state was tentatively deduced under the assumption that the paramagnetic correction factor for a free Ho3 +  ion is applicable to the present case. The independent A22 measurement for the 633 − 362 keV γ cascade for the sign assignment of the Larmor frequency is inconsistent with that from known multipolarities and mixing ratios for this cascade, implying that the mixing ratios may be different from the reported values.
