Some Gamma-Ray Cascades in ${\mathrm{Rh}}^{103}$, ${\mathrm{Ce}}^{140}$, and ${\mathrm{Dy}}^{160}$

The 445-53 keV cascade in ${\mathrm{Rh}}^{103}$ was found to have an intensity <0.5 relative to 1000 for the intensity of the most intense, 498-keV, gamma ray in the decay scheme. No evidence was found for a 323-keV gamma ray in this scheme. Spins of $\frac{5}{2}$ for the 538-keV level and $\frac{7}{2}$ for the 650-keV level in ${\mathrm{Rh}}^{103}$ are assigned in keeping with the relative intensities of <0.5 and 4 for the 445- and 538-keV gamma rays, respectively. Cascades of 1088-814, 1415-487, and 1596-306 keV have been observed in ${\mathrm{Ce}}^{140}$ and a level at 3498 keV introduced into the scheme. The beta feed to this level is estimated to be ∼0.002% of the most intense beta group in the decay of ${\mathrm{La}}^{140}$. Cascades of 87-1312 and 197-1200 have been observed in ${\mathrm{Dy}}^{160}$ and a level at 1484 keV is introduced.
