The electric dipole response of nuclei is dominated by the collective excitation mode known as the giant dipole resonance. This resonance accounts for most of the electric dipole strength and can be interpreted as a harmonic oscillation of protons against neutrons. However, a question arises when considering the addition of extra neutrons to nuclei: How does this impact the dipole...
High energy-resolution proton inelastic scattering experiments with E$_p$ = 200 MeV were performed on the even-even Nd isotope chain and $^{152}$Sm. The relativistic Coulomb excitation experiments focused on the excitation-energy region of the IsoVector Giant Dipole Resonance (IVGDR) and made use of the zero-degree mode of the K600 magnetic spectrometer at iThemba LABS. A goal of the...
One of the fundamental properties of excited nuclear quantum states is their lifetime which is related to the level width. A precise measurement of this width for key-states of light isotopes is of fundamental importance. Level widths and decay strengths are not only important observables for classifying the structure of atomic nuclei, but they can also serve as a crucial test of the modeling...
Despite giant progresses, nuclear structure physics faces a number of challenges, one of which is the role of clusters configurations in the structure of light and medium mass nuclei and the progressive disappearance with growing A of clusters states in favor of single-particle or collective excitations. The relevance of nuclear molecules has been highlighted in various disconnected...
