Branching Ratio of theγRays from the 184.6-keV State inZn67

Using a high-resolution photon spectrometer, the relative intensity of the 91.3- and 93.3-keV $\gamma$ rays from the decay of ${\mathrm{Ga}}^{67}$ has been measured as $\frac{I_{\gamma }\mathrm{}\left(91.3\right)\mathrm{}}{I_{\gamma }\mathrm{}\left(93.3\right)\mathrm{}}=(8.5\mathrm{}\pm 0.8)\%$. From this result, the branching ratio of the transitions depopulating the 184.6-keV state of ${\mathrm{Zn}}^{67}$ was deduced as $\frac{I\left(91.3\right)\mathrm{}}{I\left(184.6\right)\mathrm{}}=\frac{3.5}{24.2}$. The internal conversion coefficients for the nearly pure $M1\mathrm{}$ 91.3-keV transition are given. Several apparent discrepancies in the literature are discussed.
