Abstract
We discuss the analogy between the transfer of nucleon pairs in reac- tions involving superfluid nuclei and the transfer of electron pairs through Josephson junctions, based on measured and theoretical probabilities for one- and two-neutron transfer in the reactions 116Sn(60Ni,61Ni)115Sn and 116Sn(60Ni,62Ni)114Sn. We con- sider the possibility of the emission of γ-radiation, analogous to the emission of mi- crowave radiation in the Josephson effect. We implement the quantum mechanical description of the coupling of the electric dipole associated with the (2n)-transfer reaction process, establishing the connection between the dynamics of the collision process and the number and energy dependence of the emitted photons. We present predictions of the angular distributions, analyzing powers and strength functions of the emitted γ-radiation.
