12. Fusion hindrance in medium-light systems as a path toward the lighter cases of astrophysical interest

Prof. Giovanna Montagnoli (UNIPD)

The physics underlying the fusion hindrance phenomenon [a] and, consequently, its features
in the various systems, as well as their link to different nuclear structure situations, may be related to the Pauli exclusion principle [b], but it has not yet been fully clarified. Furthermore, we know that its existence in the fusion of light systems may have significant consequences in astrophysics...

19. Channel-Coupling Effects in Low-Energy 12C+12C Fusion Reactions

Low-energy $^{12}\mathrm{C}+^{12}\mathrm{C}$ fusion reactions play a crucial role in astrophysical phenomena such as X-ray superbursts (XRSBs), the evolution of massive stars, and Type Ia supernovae. In this reaction, resonance contributions dominate the fusion cross section, and channel-coupling effects are expected to be essential.

We theoretically investigate the...

28. Fusion of $^{12}$C + $^{16}$O at extreme sub-barrier energies

The $^{12}$C + $^{16}$O reaction plays a particularly important role in both the carbon and oxygen-burning phases of stars. Fang et al. measured this reaction in a thick-target experiment a few years ago, with both singles and particle-γ coincidence techniques down to a few nanobarns. However, the lowest energy points suffer from large experimental uncertainties which prevent discriminating...
