Nuclear spectroscopy, that has a large tradition at the Laboratori Nazionali di Legnaro, has shown in the last decades its huge potential to scrutinise the nuclear Hamiltonian. Thanks to the methods of $\gamma$-ray spectroscopy it has been possible to test such interaction in nuclei at very high spin and with large isospin values (exotic nuclei). The continuous improvement in germanium...
The physics of neutrinoless double beta (0νββ) decay has important implications on particle physics, cosmology and fundamental physics. In particular, it is the most promising process to access the effective neutrino mass. To determine quantitative information from the possible measurement of the 0νββ decay half-lives, the knowledge of the Nuclear Matrix Elements (NME) involved in the...
Modern ab initio theory in low energy nuclear physics is based on two addressing main challenges: defusing the nuclear force consistently from QCD (the residual string force between confined nucleons being the relevant degrees of freedom) and providing reliable first principle solutions of the associated many-body problem.
Crucial advances on both problems over the last 20 years have allowed...
Quadrupole interaction between protons and neutrons drives the nucleus into deformed configurations at low excitation energies. The $^{83}$Se nucleus is at the mid of the proton fp-shell (Z=28-40), it is a good candidate to study the properties of particle-hole intruder states lowered in energy by large quadrupole correlations. Lifetime measurement of the low-lying intruder state with spin...
