Directional Correlation of Gamma Rays fromSn116

The directional correlations of successive gamma rays from ${\mathrm{Sn}}^{116}$ have been measured. ${\mathrm{Sn}}^{116}$ decays via 1.09-Mev—1.27-Mev, 1.49-Mev—1.27-Mev, 0.80-Mev—1.27-Mev and 0.40-Mev—2.09-Mev gamma cascades following beta decay from 54-minute ${\mathrm{In}}^{116m}$. The measured directional correlation functions are in agreement with those expected for $4\left(Q\right)2\left(Q\right)0$, $4\left(Q\right)2\left(Q\right)0$, 2(10% $D$, 90% $Q$, 0° phase) $2\left(Q\right)0$ and 2(4% $D$, 96% $Q$, 0° phase) $2\left(Q\right)0$ spin sequences, respectively.
