Gamma spectroscopy ofFe52,Mn52, andCr52fromα+Cr50reactions

The ${}_{}{}^{50}{}_{}{}^{}\mathrm{Cr}(\alpha , 2n\gamma ){}_{}{}^{52}{}_{}{}^{}\mathrm{Fe}$ reaction has been used at incident energies of 23.5 and 27.2 MeV to search for states in ${}_{}{}^{52}{}_{}{}^{}\mathrm{Fe}$. Triple coincidence data were obtained. The first $2^{+}$ and $4^{+}$ states were located at 848.3 ± 0.9 and 2383.3 ± 1.3 keV, respectively. No $\gamma$ rays from higher spin ${}_{}{}^{52}{}_{}{}^{}\mathrm{Fe}$ states were detected. A number of $\gamma$ rays associated with states populated in the ($\alpha , \mathrm{pp}\gamma$) and ($\alpha , \mathrm{np}\gamma$) reactions were observed. Two previously unreported states were located at 6452.1 ± 0.7 and 4163.7 ± 0.5 keV in ${}_{}{}^{52}{}_{}{}^{}\mathrm{Cr}$ and ${}_{}{}^{52}{}_{}{}^{}\mathrm{Mn}$, respectively. The relative yields of many $\gamma$ rays were consistent with compound nucleus evaporation calculations.
