In nuclear astrophysics, the cosmological lithium problem is widely studied. However, the serious anomaly of around three times in the observed $^7$Li abundance, as compared to the big-bang nucleosynthesis theory is unsolved for decades. Recent revisit to the problem searched for resonances in the destruction channel $^7$Be + d. We carried out the measurements of relevant resonances in the...
One of the key quantum numbers that characterizes the state of a nucleus, and therefore is fundamental to understand its structure is the isospin. The limits of validity of the isospin symmetry is still an open question. In this context, the exploration of isotopes close to the $N = Z$ line can shed some light on the mechanism of isospin mixing. One isotope of very high interest in the context...
Nucleosynthesis of the elements beyond $\mathrm{Fe}/\mathrm{Ni}$ is mainly due to neutron capture processes, with most elements created either through the rapid neutron capture process (r-process) or the slow neutron capture process (s-process) [1]. More recent astronomical observations calls for a third, intermediate neutron capture process (i-process) to explain the elemental composition of...
Proton emission is, a priori, a contradictory decay process in neutron-rich nuclei that move the system away from the Valley of Stability instead of closer to it. However, for a handful of nuclei the last neutron is so weakly bound that the energy window for this exotic decay mode is open. These are the so-called halo nuclei, since the last nucleon(s) orbit so far away from the core that can...
