Investigating the strength of the scissors mode in 151 Sm

Abstract Change in nuclei deformation leads to changes in statistical properties such as the nuclear level density (NLD) and γ-ray strength function (γSF). The NLD and γSF of 151 Sm were extracted using the Oslo method. The strength of the scissors resonance (SR) and its centroid energy for 151 Sm w...

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