Experimental studies of the Pygmy Dipole Resonance
2013, Progress in Particle and Nuclear PhysicsCitation Excerpt :Around 8%–10% of the energy-weighted sum rule is found in this energy region, which is in good agreement with the shell-model prediction of Sagawa and Suzuki [141] shown as the solid curves. The lower frame shows the integrated strength relative to the cluster sum-rule limit [142,143] assuming a 16O core plus excess neutrons. A large fraction of this sum rule is exhausted but with decreasing trend for the more neutron-rich isotopes.

2004, Annals of PhysicsCitation Excerpt :The potential was fitted to the s wave nucleon–nucleon phase shifts only; the interaction between the neutrons in the states with relative orbital angular momentum lx>0, is neglected. We also make use of a bit different Gaussian potential suggested in [44,45] with V0=31.00 MeV and R=1.8 fm in the singlet state and V0=71.09 MeV and R=1.4984 fm in the triplet state. The singlet component of this potential was employed in our 11Li studies.
