Through this letter of intent, we propose to investigate the electromagnetic properties of the low-lying states in $^{82}$Se, which is a candidate for the possible $0\nu\beta\beta$ decay to $^{82}$Kr, via a multi-step Coulomb excitation measurement with AGATA and SPIDER. The primary objective is to measure, with suitable accuracy, the diagonal and transition E2 matrix elements connecting the...
Neutrinoless double-beta ($0\nu\beta\beta$) decay is a speculated, extremely rare nuclear phenomenon, which can only occur if neutrinos are massive Majorana particles. Theoretical works have shown that the decay rate is extremely influenced by the nuclear shape of the decay partners. In this context, the $^{116}$Cd$\to ^{116}$Sn decay is expected to be a good candidate to observe such an...
Abstract
Understanding the structure of near-threshold narrow resonances in C, O and B isotopes is of great importance for nuclear structure studies (e.g., in connection with the onset of collectivization phenomena in cluster nuclei) as well as nuclear astrophysics. In this context, the $\gamma$ decay from near-threshold states, with branches of the order of 10$^{-3}$ – 10$^{-6}$ with...
