Magnetic Moment of the 1.409-MeV2+State ofFe54

Abstract

The $g$ factor of the first excited $2^{+}$ state of ${}_{}{}^{54}{}_{}{}^{}\mathrm{Fe}$ has been measured to be $g=1.43\mathrm{}\pm 0.28$. The $0\to 2\to 0$ (${}_{}{}^{16}{}_{}{}^{}\mathrm{O},\gamma$) angular correlation through the 1.4-psec mean-life state was precessed using the transient magnetic field effective in iron on Coulomb-excited and recoiled ${}_{}{}^{54}{}_{}{}^{}\mathrm{Fe}$. This result is in agreement with a quite pure ${\left(f_{\frac{7}{2}}\right)}^{-2\mathrm{}}$ shell-model configuration for the state.
