“…More recently, two-nucleon transfer reactions have been analyzed within the CRC formalism, mostly with the computer code FRESCO ( [46,47,67,68,70,[85][86][87][88]). In [85], the authors describe p-6 He scattering at very low energy (0.97 MeV in the CM frame) including explicitly elastic, inelastic and transfer channels.…”

The second-order distorted wave Born approximation implementation of two-particle transfer direct reactions which includes simultaneous and successive transfer, properly corrected by non-orthogonality effects, is tested with the help of controlled nuclear structure and reaction inputs against data spanning the whole mass table, and showed to constitute a quantitative probe of nuclear pairing correlations.

“…4, it seems fair to posit that two-nucleon transfer reaction theory has reached a quantitative level. Within this context, it is important to remind of the fact that many groups have contributed through the years to develop the reaction theory of two-nucleon transfer processes including simultaneous, successive and non-orthogonality contributions into a tool to calculate the absolute differential cross sections which can be directly compared with the experiment findings (see 36,[39][40][41][42][43][44][45][46][47][48][49] and refs. therein; see also the Chapter of Thompson in this Volume).…”

Making use of the fact that the collective modes associated with the spontaneous (static and dynamic) violation of gauge invariance in atomic nuclei (pairing rotations and pairing vibrations), are amenable to a simple, quite accurate nuclear structure description (BCS and QRPA respectively), it is possible to quantitatively test the reaction mechanism which is at the basis of two-nucleon transfer reactions, specific probe of pairing in nuclei. With the help of the static and dynamic mean field spectroscopic amplitudes, taking into account successive and simultaneous transfer channels properly corrected because of nonorthogonality effects, as well as describing the associated elastic channels in terms of experimentally determined optical potentials, one obtains absolute, two-particle transfer differential cross sections which provide an overall account of the data within experimental errors. One of the first results connected with such quantitative studies of pairing correlations in nuclei is the observation of phonon mediated pairing in the exotic halo nucleus 11 Li, and the associated discovery of a new mechanism to break nuclear gauge symmetry: bootstrap, pigmy-resonance-mediated Cooper pair binding. Gauge invariant BCS nuclear theory:Pairing vibrations and pairing rotationsA closed shell system like, e.g., 132 Sn (virtually) spends part of the time in the ground state of 134 Sn and part in that of 130 Sn. This is another way to say that addition and removal pairing vibrations, are J π = 0 + , τ = 1, β = ±2 elementary modes of nuclear excitation, τ and β being the isospin and the particle (fermion) quantum numbers.

“…In particular, transfer reactions, in which the projectile transfers one or more nucleons to or from the target nucleus, provide access to nuclear spectroscopic amplitudes. Reactions with light ions like (p,t) and (t,p) have been extensively used to study pairing correlations in proton-rich and neutronrich nuclei, respectively [3][4][5][6][7][8][9][10][11][12][13]. Such types of reactions are advantageous because, from the experimental point of view, detection of light particles provides good energy resolution and clear particle identification.…”

“…However, nowadays, the use of triton beams is strongly limited due to radiation safety. Other light neutron-rich projectiles like 6 He, 8 Li, and 10 Be are exotic nuclei and therefore beam intensities are usually too low for measurements of nuclear reactions involving transfer of nucleons. Within this scenario, the ( 18 O, 16 O) reaction is a promising option.…”

Recently a quantitative description of the two-neutron transfer reaction 12 C( 18 O , 16 O) 14 C was performed and the measured cross sections were successfully reproduced [M. Cavallaro et al., Phys. Rev. C 88, 054601 (2013)]. This task was accomplished by combining nuclear structure calculations of spectroscopic amplitudes and a full quantum description of the reaction mechanism. Verification of such a theoretical approach to other heavy nuclear systems is mandatory in order to use ( 18 O , 16 O) reactions to assess pair configurations in nuclear states. In this work we apply this methodology to the 16 O( 18 O , 16 O) 18 O reaction at 84 MeV. Experimental angular distributions for the two-neutron transfer to the ground state and 2 + 1 state of 18 O were obtained using the MAGNEX spectrometer at INFN-LNS. The roles of one-and two-step processes are analyzed under the exact finite range coupled reaction channel and the second order distorted wave Born approximation. We conclude that the one-step transfer mechanism is dominant in this system.
