| Abstract: | The g-factor of the first excited state of 93Sr (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 Larmor frequency
ω
L = (2.60 ± 0.15) × 108 rad/s was obtained. The g-factor is derived as g = −0.227 ± 0.013 from g = −ℏω

N. If the spin of the first excited state of 93Sr 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. |
