Abstract Core-collapse supernovae are among the most magnificent events in observable universe. They produce many of chemical elements necessary for life to exist and their remnants—neutron stars black holes—are interesting astrophysical objects own right. However, despite millennia observations almost a century study, explosion mechanism core-collapse is not yet well understood. Hyper-Kamiokande next-generation neutrino detector that will be able observe flux from next galactic supernova...
Background: Heavy-ion induced two-nucleon transfer reactions are powerful tools to reveal peculiar aspects of the atomic nucleus, such as pairing correlations, single-particle and collective degrees freedom, more. Also, these processes in competition with direct meson exchange double charge reactions, which have recently attracted great interest due their possible connection neutrinoless double-\ensuremath{\beta} decay.

The 40 Ca( 18 O, F) K single charge exchange (SCE) reaction is explored at an incident energy of 275 MeV and analyzed consistently by collecting the elastic scattering inelastic data under same experimental conditions. Full quantum-mechanical SCE calculations direct mechanism are performed including microscopic nuclear structure inputs adopting either a bare optical potential or coupled channel equivalent polarization (CCEP) constrained data. describes magnitude shape angular distributions...
Two-nucleon transfer reactions are essential tools to investigate specific features of the nuclear structure, such as correlation among valence particles in process. Besides, may be an important channel take into account charge-exchange processes since they can represent a competing contribution final cross section.

Double charge exchange (DCE) reactions could provide experimentally driven information about nuclear matrix elements of interest in the context neutrinoless double-β decay. To achieve this goal, a detailed description reaction mechanism is mandatory. This requires full characterization initial and final-state interactions, which are poorly known for many projectile-target systems involved future DCE studies. Among these, we intend to study 20Ne + 130Te 18O 116Sn at 15.3 AMeV, particularly...
We have measured the elastic scattering of weakly bound $^{6}\mathrm{Li}$ on $^{116,112}\mathrm{Sn}$ targets, at energies close to Coulomb barrier. The energy dependence interaction potential has been investigated by two different methods and presence breakup threshold anomaly is observed. also derived total reaction cross sections for above systems compared them those other with halo, bound, tightly projectiles targets similar masses. are largest halo nuclei, then no-halo smallest systems.

Mass distributions of fission fragments arising from the slow quasifission (SQF) process, derived by comparing measured data with theory for several reactions, show distinct features. Irrespective fissioning systems, peak corresponding to lighter in SQF mass distribution is found be always at $A\ensuremath{\approx}96$, whereas position heavier increases linearly dinuclear system. Further, yield events decreases increasing projectile energy. These observations within certain model dependence...
Full angular distributions for elastic and inelastic scattering of $^{11}\mathrm{B}$ on $^{58}\mathrm{Ni}$ have been measured at different bombarding energies around the Coulomb barrier.
