2. Shape coexistence in $^{82}$Se and its relevance in the $^{82}$Se $\to$ $^{82}$Kr $0\nu\beta\beta$ decay

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...

10. Development of Self-calibration technique for AGATA via Coulomb excitation

We propose to develop a new signal basis for AGATA array via Coulomb excitation of $^{28}$Si on a thin $^{197}$Au target using the AGATA + PRISMA setup at LNL. The new signal basis will be obtained in an experimental way using the newly developed self-calibration technique from a long-time $\gamma$-source calibration data. The performance of the new self-calibration basis will be studied from...

13. Search for the $\gamma$ decay of the narrow near-threshold resonance in $^{11}$B

Giacomo Corbari (Università degli Studi di Milano and INFN)

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...
