The energies and relative intensities of the primary gamma rays from the 44 Sm(n, gamma ) 145 Sm reaction have been measured with a Ge(Li) pair-formation gamma -ray spectrometer from 3.0-7.2 MeV. The neutron separation energy of 145 Sm was found to be 6757.1+or-0.3 keV. A comparison of the measured strengths of excitation of levels in 145 Sm in the (n, gamma ) and (d,p) reactions reveals that they are strongly correlated. These results are discussed in terms of a number of simple neutron-capture reaction mechanisms.
