Measurement of thegFactor for the1.1−μsecShape Isomeric State inPu237

Abstract

The spin precession of the $1.1-\mu sec$ shape isomeric state in ${}_{}{}^{237}{}_{}{}^{}\mathrm{Pu}$ has been measured by the perturbed angular correlation method. From a measurement of the spin rotation frequency as a function of temperature of the target, the paramagnetic correction factor $\beta$ has been determined to be in agreement with the theoretical value of 2.86 at room temperature for a $4^{+}$ ionic state. The deduced value for $g$ is +0.14 ± 0.02.
