Investigations of Spin Assignments inCa41,Cr53, andFe55

The angular correlations of $\gamma$ rays from ($d,p\gamma$) reactions with 3-MeV deuterons to states in ${}_{}{}^{41}{}_{}{}^{}\mathrm{Ca}$, ${}_{}{}^{53}{}_{}{}^{}\mathrm{Cr}$, and ${}_{}{}^{55}{}_{}{}^{}\mathrm{Fe}$ have been measured utilizing a collinear geometry and a Ge(Li) $\gamma$-ray detector. This study was undertaken in an attempt to resolve conflicts in spin assignments between vector-analyzing-power measurements and other measurements. Results indicate $J=\frac{1}{2}$ for the 3618-keV level in ${}_{}{}^{53}{}_{}{}^{}\mathrm{Cr}$ and the 3788-keV level in ${}_{}{}^{55}{}_{}{}^{}\mathrm{Fe}$ in agreement with the vector-analyzing-power measurements. The conflict is not resolved in the case of the 3614-keV level in ${}_{}{}^{41}{}_{}{}^{}\mathrm{Ca}$. There is a strong possibility that there are two unresolved levels in this region, one with $J=\frac{1}{2}$ and the other with $J=\frac{3}{2}$.
