68. (online) Superallowed $^{10}$C β-decay branching ratio measurement at INFN-LNL: report of Exp. 22. 72 and 24. 12

We report preliminary results from the measurements of the superallowed $^{10}$C β-decay branching ratio with the AGATA HPGe tracking array at INFN-LNL. The precedent experiment, Exp. 22. 72 was performed in June 2023. A 10-MeV proton beam accelerated from the Tandem-XTU impinged to a 1-mg/cm$^2$-thick, Au-sandwiched $^{10}$B target. The experiment was run in two modes: in-beam mode and decay...

62. (online) Report on the AGATA experiment number 24.027

Inverse beta decay (IBD) is a crucial process historically employed to study neutrinos.
For example, discrepancies between measured and expected IBD rates on ($^{71}\text{Ga}$), the so-called gallium anomaly, suggest the possible existence of sterile neutrinos. A recent publication showed that the poorly known associated Nuclear Matrix Element (NME) can be extracted measuring the decay...

12. Report on the AGATA experiment number 23.011

We present the preliminary analysis of an experiment performed at INFN LNL in November 2023 aimed at studying the two-octupole phonon collectivity in $^{96}$Zr. The goal of the experiment was to perform a $\gamma$-decay branching ratio measurement from the 6$^+$ to the 3$^-$ state, so as to extract the B(E3; 6$^+\rightarrow3^-$) value. If large, this parameter would indicate for the level to...

77. Search for a nuclear Josephson effect in 60Ni+116Sn sub-barrier transfer reactions with the PRISMA+AGATA set-up

Sub-barrier transfer experiments have been recently carried out at LNL in the 60Ni+116Sn system, where the two neutron transfer channel is well Q-value matched. Reaction products have been detected in inverse kinematic and at forward angles with the large solid angle magnetic spectrometer PRISMA, providing high efficiency and resolution. In these studies one follows the behavior of the...
