Half-life and Magnetic Moment of the First Excited State in 132I

The half-life and the magnetic moment were measured for the first excited state in $^{132}\mathrm{I}$, of which the inconsistent results on the half-life have been reported by several other groups. This time, measurements were performed on $^{132}\mathrm{I}$ obtained as a decay product of a $^{132}\mathrm{Te}$ radioactive beam from the ion guide at Tohoku University. The half-life of this level was determined to be ${T}_{1/2}=1.120\ifmmode\pm\else\textpm\fi{}0.015$ ns using a conventional coincidence technique with a pair of BaF${}_{2}$ detectors. The time-differential perturbed angular correlation technique was successfully applied to the first excited state in $^{132}\mathrm{I}$ implanted into nickel foils. The magnetic moment of this state was determined to be $\ensuremath{\mu}=+(2.06\ifmmode\pm\else\textpm\fi{}0.18){\ensuremath{\mu}}_{N}$. The present results are consistent with values reported by Gorodetzky et al. and Singh et al.
