“…The particle(s) and cluster pickup and stripping are among the most studied reactions because of their sensitivity to the nuclear structure of the interacting partners. Two-nucleon transfer reactions have gained special attention because they can probe pairing correlations in nuclei [3][4][5][6][7][8][9][10][11][12][13]. In addition, they are relevant to model more complex processes such as double charge exchange reactions, which are of interest for applications in neutrinoless double beta decay researches [14,15].…”

Recently, various two-neutron transfer studies using the (18 O, 16 O) reaction were performed with a large success. This was achieved because of a combined use of the microscopic quantum description of the reaction mechanism and of the nuclear structure. In the present work we use this methodology to study the two-neutron transfer reaction of the 18 O + 64 Ni system at 84 MeV incident energy, to the ground and first 2 + excited state of the residual 66 Ni nucleus. All the experimental data were measured by the large acceptance MAGNEX spectrometer at the Instituto Nazionale di Fisica Nucleare-Laboratori Nazionali del Sud (Italy). We have performed exact finite range cross section calculations using the coupled channel Born approximation (CCBA) and coupled reaction channel (CRC) method for the sequential and direct two-neutron transfers, respectively. Moreover, this is the first time that the formalism of the microscopic interaction boson model (IBM-2) was applied to a two-neutron transfer reaction. From our results we conclude that for two-neutron transfer to the ground state of 66 Ni, the direct transfer is the dominant reaction mechanism, whereas for the transfer to the first excited state of 66 Ni, the sequential process dominates. A competition between long-range and short-range correlations is discussed, in particular, how the use of two different models (Shell model and IBM's) help to disentangle long-and short-range correlations.

“…In some of them the direct (one-step) process was found to be the dominant transfer mechanism (see, for example, Refs. [3,6]). In other works, the two-step process (sequential) was found to be the more important one (see, for example, Ref.…”

“…In case of one cluster outside the core, the interfering transfer reaction is simultaneous or one-step transfer but if transfer takes place in two step by transfer of n/p and p/n one after other it is termed as sequential transfer. The individual contribution of sequential transfer can be comparable or even more than the single step direct transfer/emission [21][22][23][24][25] which also depends on kinematic parameters. The sequential transfer calculations were included to emphasis the understanding of the relative importance of the processes governed by transfer mechanism.…”

Inclusive α-production cross-section has been measured for 6 Li+ 51 V system near coulomb barrier. Theoretical calculations for contributing reaction channels were performed using finite range coupled reaction method from FRESCO code to understand the reaction mechanisms. Cross-section from breakup(α+d) and 1-n, 1-p, 1-d and sequential (n+p or p+n) transfer and statistical decay channel leading to α-production were estimated to get the cumulative production cross-section. It is observed that these channels could reproduce the integral α-production and their angular distributions quite well. The sequential transfer shows a dominant contribution compared to direct transfer channels.

“…For instance, even elastic scattering was found to have a strong coupling to the band members in deformed nuclei, which alters the Fresnel type angular distribution. A long standing problem of absolute cross sections of two-nucleon transfer reactions, like (p,t), and ( 18 O, 16 O) [22,23], have been identified by successive processes. Even for the cross sections of the ground state transitions of the ( 18 O, 16 O) reactions the successive transfer contributions comprises nearly half of them.…”

The role of nuclear clustering is discussed for nucleosynthesis in stellar evolution with the previously proposed Cluster Nucleosynthesis Diagram (CND). I mainly discuss -cluster nature for nucleosynthesis, which can be investigated by two experimental methods, alpha resonant elastic scattering and direct alpha transfer reactions. Specifically, we present the important role of  cluster resonance in the (,p) reactions. The applicability of direct cluster transfer reactions are also discussed in terms of the reaction mechanism. Some possibilities are also discussed for the investigation of O-and C-burning with massive transfer reactions.
