A detailed description of the properties of dense matter in extreme conditions, as those within Neutron Star cores, is still an open problem, whose solution is hampered by both the lack of empirical data and by the difficulties in developing a suitable theoretical framework for the microscopic nuclear dynamics in such regimes. The detection of gravitational waves from the first observed...
Heavy ion double charge exchange reactions are described by sequential meson-exchange, corresponding to a double single charge exchange (DSCE) reaction mechanism. The theoretical formulation of second-order nuclear reactions and its application to DSCE is represented by a fully quantum mechanical distorted wave 2-step process (second order DWBA). Special emphasis is given to the role of...
L'accuratezza di diversi modelli astrofisici, come quelli che descrivono le abbondanze degli elementi nell'Universo, è limitata dalla conoscenza delle sezioni d'urto di un ampio numero di reazioni nucleari, spesso riguardanti reagenti carichi e leggeri a basse energie di collisione ($< 100$ keV). La dinamica di reazione in tale regime è dominata dalla penetrazione della barriera Coulombiana....
The JLab experiment PREX-II, extension of the experiment PREX, measured for the first time, in a model independent way, the neutron skin of the nucleus 208Pb. The existence in heavy nuclei of a neutron skin, that is of a positive difference between the radii of the neutron and proton distributions, was supposed to exist since many years, but up to PREX and PREX-II measurements, its...
