Abstract

The nuclear level structure of 54Cr was studied by thermal-neutron capture gamma-ray spectroscopy of an enriched sample of 53Cr and compared with a natural chromium sample by means of a Ge(Li) spectrometer, using an external beam at the SAFARI-1 reactor. Eighty of the ninety observed transitions allocated to 54Cr (as compared with the previously observed total of 42) could be placed in a level and decay scheme, representing more than 99% of the total observed intensity. The energy precision of several levels observed in other reactions was improved and limits were imposed on their spins. The sensitivity of the experiment allowed the observation of low-lying levels up to spin 4. A new level is proposed at 3925.5 keV, close to the known level of 3927.6 keV. Improved gamma branching ratios were obtained for a number of levels. The neutron binding energy was found to be in agreement with previous determinations.
