Abstract
We have investigated theγ-rays from the decay of 46-min51Mn produced by the50Cr (d, n) reaction. Twelveγ-rays were observed. Theseγ-rays have been incorporated into a level scheme of51Cr with levels at 0, 749.1, 1164.4, 1353.3, 1557.4, 1899.4, 2001.4, 2312.5 and 2829.7 keV. Branching ratios, logft values, and jπ assignments are discussed for these levels. The lifetime of the 749.1 keV level was measured to be T1/2=7.6 ± 0.3 ns by utilizing the51V(p, n γ 51Cr reaction produced by a 3.8 MeV pulsed proton beam. The 749 keV,E2 transition is hindered by a factor of 34 compared to the Weisskopf estimate.
