| Περίληψη: | Sub-barrier transfer experiments have been recently carried out at LNL in the 60Ni+116Sn system. Using inverse kinematics, target-like reaction products are detected with the spectrometer PRISMA, studying the behavior of the transfer probabilities by varying the internuclear distance. Very recently, the coupling of the AGATA array to PRISMA offered a unique opportunity to study a nuclear Josephson-like effect, with Cooper-pair tunneling between superfluid nuclei, whose manifestation has been recently proposed using the 60Ni+116Sn data as a stepping stone. Predictions have been made of a specific γ-ray strength function associated with the dipole oscillations generated by the two neutron transfer process. We directly tested for the first time the possible manifestation of this important effect of Cooper pair behavior, observed to date only in condensed matter physics. The experiment has been carried out with very high statistics at a bombarding energy below the Coulomb barrier, corresponding to a distance of closest approach close to the estimated correlation length, exploiting the unique characteristics offered by the PRISMA+AGATA setup in terms of resolution and efficiency.
