Session 2: Nuclear Structure, Reactions and Dynamics

Studies of nuclear excited states using High-resolution light-ion reactions have extensively been performed at RCNP and iThemba LABS in the past decades. Both facilities are unique for realizing zero-degree inelastic scattering experiments using proton or alpha particles and for the high-resolution capability of 20 keV.
For example, the proton-scattering experiment at zero degrees [1] has...
Inelastic proton scattering at very forward angles is an excellent tool for studying the dipole response in nuclei [1]. Reactions with intermediate proton energies of a few hundred MeV and scattering angles close to 0$^\circ$ are particularly suited to investigate the isovector spin-flip M1 resonance due to the strong spin-isospin dependent part of the effective proton-neutron interaction in...
The pygmy dipole resonance (PDR) is a cluster of 1- states around and below the neutron separation energy and has gained traction in nuclear structure studies. The microscopic nature of the PDR is still an open question in particular, whether these 1- states could be defined as collective or being dominated by specific single-particle configurations. The study here presented is one of the...
We briefly review the properties of the low-lying dipole states known as Pygmy Dipole Resonance trying to select the main one which could define this new excitation mode. A good candidate seems to be the isoscalar-isovector mixing which has been proved by both theoretical and experimental investigations. On the other hand, the study of the low-lying quadrupole states do not seem to provide...
At the Radioactive Isotope Beam Factory at the RIKEN Nishina Center in-beam gamma-ray spectroscopy experiments take advantage of the wide range of radioactive ion beams produced by the projectile fragmentation and fission. Isotopes of interest are separated by the BigRIPS fragment separator and guide to a secondary target. Reaction residues are identified either in the ZeroDegree spectrometer...
