Decay Scheme ofIn107

The gamma radiations of ${\mathrm{In}}^{107}$ have been investigated with a scintillation spectrometer. The ${\mathrm{In}}^{107}$ was produced in a cyclotron by a ($d, n$) reaction on electromagnetically enriched ${\mathrm{Cd}}^{106}$. Beta-gamma and $\gamma -\gamma$ coincidence experiments showed, in addition to the annihilation radiation, only one $\gamma$ ray of 0.22-Mev associated with the 2-Mev positron.
