Pair neutron transfer in 60Ni+116Sn probed via gamma-particle coincidences

We performed a gamma-particle coincidence experiment for the 60Ni+116Sn system in order to investigate whether the population of the two-neutron pick-up channel leading to 62Ni is mainly concentrated in the ground state transition, as has been found in a previous work. The experiment has been performed by employing the PRISMA magnetic spectrometer coupled to the Advanced Gamma Tracking Array (AGATA) demonstrator. The strength distribution of excited states corresponding to the inelastic, one- and two-neutron transfer channels has been extracted. We found that in the two-neutron transfer channel the strength to excited states corresponds to a fraction (less than 24%) of the total, consistent with the previously obtained results that the 2n channel is dominated by the ground to ground state transition
