“…Heavy-ion multinucleon transfer reactions have been extensively studied during recent years [1][2][3][4][5][6][7][8], revealing interesting phenomena connected to single-particle pairing correlations and cluster degrees of freedom. Moreover, these studies are also complementary to those on double charge exchange (DCE) reactions, which have recently attracted interest for their possible connection to neutrinoless double-β decay [9][10][11][12][13].…”

Background: Heavy-ion induced two-nucleon transfer reactions are powerful tools to reveal peculiar aspects of the atomic nucleus, such as pairing correlations, single-particle and collective degrees of freedom, and more. Also, these processes are in competition with the direct meson exchange in the double charge exchange reactions, which have recently attracted great interest due to their possible connection to neutrinoless double-β decay. In this framework, the exploration of two-nucleon transfer reactions in the 20 Ne + 116 Cd collision at energies above the Coulomb barrier is particularly relevant since the 116 Cd nucleus is a candidate for the double-β decay.Purpose: We want to analyze selected transitions to low-lying 0 + and 2 + states of the residual nuclei in the 116 Cd( 20 Ne, 22 Ne) 114 Cd two-neutron pickup and 116 Cd( 20 Ne, 18 O) 118 Sn two-proton stripping reactions at 306 MeV incident energy and determine the role of the couplings with inelastic transitions. Methods: We measured the excitation energy spectra and absolute cross sections for the two reactions using the MAGNEX large acceptance magnetic spectrometer to detect the ejectiles. We performed direct coupled reaction channels and sequential distorted wave Born approximation calculations using the double folding São Paulo potential to model the initial and final state interactions. The spectroscopic amplitudes for two-and singleparticle transitions were derived by different nuclear structure approaches: microscopic large-scale shell model, interacting boson model-2 and quasiparticle random phase approximation. Results:The calculations are able to reproduce the experimental cross sections for both two-neutron and twoproton transfer reactions. The role of couplings with the inelastic channels are found to be important in the two-proton transfer case. A competition between the direct and the sequential process is found in the reaction *

“…The result of this study is shown in Figures 1, 2, and 3, in which the 18 O was the projectile impinging on light-and medium-mass targets. Conversely, for the two-neutron transfer in the 206 Pb( 18 O, 16 O) 208 Pb reaction [16] the cross section of the sequential process was larger than the direct one. Data @84MeV IC Seq 13 The scenario is a little bit different when the two neutrons populate some excited states of the residual nuclei with strong collectivity.…”

“…It was shown that, while the elastic scattering is the predominant process at forward angles, the elastic-transfer is more likely to occur at backward angles. On the other hand, in the alpha-transfer reaction 12 C( 16 O, 12 C) 16 O, it is observed a strong competition between the elastic scattering and elastic transfer processes at backward angles. In Figure 4, we show the comparison between experimental data and theoretical predictions for the angular distribution concerning the quasi-elastic collision 7 Be+ 9 Be.…”

“…Another alternative reaction was proposed in the Istituto Nazionale di Fisica Nucleare -Laboratori Nazionali del Sud (Italy) by considering the ( 18 O, 16 O) reaction, once the 18 O nucleus can be considered as composed by an inert core of 16 O and two valence neutrons. In this sense, some reactions were measured considering the 18 O nucleus as projectile at 84 MeV incident energy, and 12,13 C [1, 2], 16 O [3,4], 28 Si [5] and 64 Ni [6] as target to analyze the feasibility of the ( 18 O, 16 O) reaction as substitute of the (t,p) one, and then to investigate the role of the pairing correlation of both transferred neutrons in the transfer reaction cross sections obtained performing coupled reaction channel calculations [7]. The 12 C( 18 O, 16 O) 14 C reaction has experimentally shown, similarly to (t,p), the feasibility in populating the twoneutron configuration of the 14 C nucleus.…”

This work presents theoretical results compared with the experimental data for the two–neutron transfer angular distribution in which a beam of 18O nucleus, at 84 MeV incident energy, has collided onthe 13C, 28Si, and 64Ni targets. The two-neutron transfer in the 9Be(7Be,9Be)7Be reaction, at 23.1 MeV incident energy, was also analyzed. The main goal was to verify the relevance of the pairing correlation of the two transferred neutrons on the cross sections and to show its role when both neutrons are transferred to states with a low and high degree of collectivity.

“…Heavy-ion transfer reactions may provide valuable information on the nuclear structure and the reaction mechanism [28][29][30][31][32][33][34][35]. Due to their high selectivity in populating specific degrees of freedom in the residual nuclei, single-nucleon transfer are well established tools for probing single-particle configurations, while two-nucleon transfer offers an insight of pairing correlations [36][37][38][39].…”

Single-nucleon transfer reactions are processes that selectively probe single-particle components of the populated many-body nuclear states. In this context, recent efforts are made to build a unified description of the rich nuclear spectroscopy accessible in heavy-ion collisions. An example of this multi-channel approach is the study of the competition between successive nucleon transfer and charge exchange reactions, the latter being of particular interest in the context of single and double beta decay studies. To this extent, the one-proton pickup reaction 48 Ti( 18 O, 19 F) 47 Sc at 275 MeV was measured for the first time, under the NUMEN experimental campaign. Differential cross-section angular distribution measurements for the 19 F ejectiles were performed at INFN-LNS in Catania by using the MAGNEX large acceptance magnetic spectrometer. The data were analyzed within the Distorted-Wave and Coupled-Channels Born Approximation frameworks. The initial and final-state interactions were described adopting the São Paulo potential, whereas the spectroscopic amplitudes for the projectile and target overlaps were derived from shell-model calculations. The theoretical cross-sections are found to be in very good agreement with the experimental data suggesting the validity of the optical potentials and the shell-model description of the involved nuclear states within the adopted model space.
