Among the hydrogen burning processes in stars, proton reactions with Ne isotopes are very relevant to constrain the production and abundances of neon and sodium isotopes in massive stars, novae and supernovae. In particular the 20Ne(p,γ)21Na reaction is the first and slowest reaction of the NeNa cycle and it controls the speed at which the entire cycle proceeds: its rate affects the synthesis ...
Light (e.g. deuterons, tritons, helions, α−particles), and heavy (pasta phases) nuclei exist in nature in core-collapse supernova matter and neutron star (NS) mergers, where temperatures of the order of 50 to 100 MeV may be attained. In the NS inner crust, that is under different conditions of temperature, density and asymmetry, these heavy clusters should also be present. The appearance of...
In this talk, we will present our work at the interface between density functional theory (DFT) and ab initio theory. In particular, we will focus on infinite nuclear matter, that we simulate using a description based on a finite number of nucleons, and discuss three research directions [1]:
1. a new ab initio Self-consistent Green's function (SCGF) approach, based on the algebraic...

Over a decade ago, the first experimental evidence for the N=32 sub shell closure in the calcium isotopic chain emerged [1,2]. Subsequent experimental and theoretical investigations have confirmed this finding. However, in laser spectroscopy measurements extending up to $^{52}$Ca (N=32), no indications of this shell gap were apparent [3]. Crossing the...
In-beam γ-ray spectroscopy of 79Cu was carried out at the Radioactive Isotope Beam Factory of the Riken laboratory during the 2021 Hicari campaign [1]. In-flight fission of 238U at 345 MeV/nucleon produced a wide range of exotic nuclei, including 80Zn. These nuclei were sent through the Bigrips separator onto a beryllium target, where knock-out reactions took place. The emitted γ-rays were...
The neutrinoless double beta decay is of fundamental importance for particle physics, nuclear physics, and cosmology. Nuclear matrix element, which encodes the impact of the nuclear structure on the decay half-life, is crucial to interpreting the experimental limits and even more potential future discoveries. However, current knowledge of the nuclear matrix element is not satisfactory due to...
