Investigating the Strength of the Scissors Mode in 151Sm

Change in nuclei deformation leads to changes in statistical properties such as the nuclear level density (NLD) and gamma-ray strength function (gamma SF). The NLD and gamma SF of Sm-151 were extracted using the Oslo method. The strength of the scissors resonance (SR) and its centroid energy for Sm-151 were found to be 2.13 +/- 0.60 mu(2)(N) and 2.48 +/- 0.25 MeV, respectively. These results were used to place the SR of Sm-151 and its magnetic dipole strength B(M1) (SR) into the context of previously measured Sm isotopes.
