Measurement Of The Magnetic Moment Of The First Excited State In Sr-93 Using On-Line Tdpac Technique

The g-factor of the first excited state of Sr-93 (E=213 keV, T-1/2=4.6 ns) was measured by an on-line TDPAC technique with use Of the strong hyperfine field in Fe metal. The Lamor frequency omega(L)=(2.60 +/- 0.15)x10(8) rad/s was obtained. The g-factor is derived as g=-0.227 +/- 0.013 from g=(h) over bar omega(L)/B-hf mu(N). If the spin of the first excited state of S-93 is assumed to be 3/2, the g-factor is predicted by a simple core-excitation model as g=-0.22, which is in good agreement with the present experimental result.
