Abstract
Gamma-ray decay of levels in the stable isotope $^{53}\mathrm{Cr}$ has been studied using $^{53}\mathrm{Cr}$(n,n'\ensuremath{\gamma}) reactions for incident neutron energies between threshold and 10 MeV. Measured gamma-ray production cross sections have been compared with earlier measurements and with cross sections calculated using precompound-compound-nucleus theory. Some of the present results are at variance with earlier experimental or evaluated results. For example, for the decay of the ${E}_{x}$=1537-keV level we are unable to explain variations in the measured branching ratios of the transition gamma rays as a function of incident neutron energy. The experimental data were analyzed within the framework of several theoretical model calculations of the level structure of $^{53}\mathrm{Cr}$. Quantitative discrepancies are discussed.
