Recent theoretical developments in the phenomenology of alpha-clustering are presented. The interplay of clustering with decay phenomena mediated by electromagnetic and weak interactions is outlined, together with its importance for modern nuclear structure and related fields.
The elastic scattering of alpha particles on N=Z nuclei exhibits a significant enhancement of the cross section at large scattering angles, a phenomenon known as anomalous large angle scattering (ALAS) [1]. Several studies [2] suggest that ALAS is linked to the alpha-like correlations present in N=Z nuclei. Moreover, this behavior cannot be satisfactorily explained within the standard...
In my talk I will present new statistical methods for assessing the values and their uncertainties of the nuclear matrix elements for neutrinoless double beta decays, two neutrino double beta decays, two neutrino double electron capture, and neutrinoless double electron capture. The analyses are made within the traditional shell model approach. Examples for 48Ca, 82Se, 124Xe, and 136Xe will be...
Pygmy Dipole Resonance in nuclear systems, related to the dipole response around neutron separation energy, was under a close scrutiny of several experimental and theoretical investigations during the last decade. Critical questions regard its nature, centroid position and width, the evolution of its features with the number of neutrons in excess, its role in the astrophysical context. We...
