Description
In a recent experiment at the NICOLE on-line nuclear orientation facility, gamma ray anisotropy and nuclear magnetic resonance measurements were made on Hf isomeric states. A HfF3 beam was used to implant separated Hf isotopes into a magnetized pure nickel foil cooled to temperatures down to ~10 millikelvin.
A new NMR/ON resonance was observed in the 8- 180mHf isomer. Angular distribution was measured for many gamma-ray transitions in the decay of this isomer and the decay of isomeric states in 177Hf.
Data analysis is in progress and preliminary results will be reported.
