“…1. The ground and excited states of the nuclei 9 Be, 6 Be, 6 Li, and 5 He were identified in the following reaction channels: 9 Be ( 3 He, 3 He) 9 Be (see panel a), 9 Be ( 3 He, 6 He) 6 Be (b), 9 Be ( 3 He, 6 Li) 6 Li (c), and 9 Be ( 3 He, 7 Be) 5 He (d). The energy calibration of and detectors was performed considering well-known states, which are strongly excited in the spectra.…”

“…CRC calculations for the transfer of the cluster t utilized the WS optical potential for the entrance channel, and a WS shaped potential for the exit channel 6 Li + 6 Li. The potential parameters of the exit channel were determined by fitting to the experimental data on the elastic scattering of 6 Li + 6 Li at an energy of 40 MeV [25]. The obtained optical potential is shown in Table 1.…”

“…In the study [13], the nuclear reactions resulting from He + 9 Be at an energy of 63 MeV have been analyzed. The elastic channel as well as the exit channels 7 Be + 5 He, 6 Li + 6 Li were calculated within the CRC method. For these channels, all the possible transfer mechanisms were supposed.…”

“…For these channels, all the possible transfer mechanisms were supposed. In particular, the two-step transfer mechanisms beginning with n pick-up effectively enhances the underestimated cross sections for the channels 7 Be + 5 He and 6 Li + 6 Li. It shows that the p-shell neutron is loosely bound, and, in turn, the nucleus 9 Be has the cluster structure 8 Be .…”

An experiment has been carried out for studying the cluster structure of 9Be induced by the 3 He ions at the energy of 30 MeV. As results of the nuclear reaction 3He + 9Be the differential cross sections for the exit channels – elastic, inelastic, α +8Be, 6He + 6Be, 6Li + 6Li, and 7Be + 5He – were measured. Elastic and inelastic scattering data are treated within both the Optical model and Coupled channels method. A new set of optical potential was taken for the elasticscattering. The deformation parameter δ2 was established for the transition 3/2 → 5/2.Cluster transfer reactions are analyzed by means of the coupled reaction channels method. The nuclear reactions with the exit channels 6He + 6Be, 6Li + 6Li and 7Be + 5He He are complemented by two-step transfer mechanisms. The contribution of each reaction mechanisms are shown, and compared with the findings of other authors.

In this review, we discuss recent advancements in the study of clustering phenomena occurring in light nuclei, and their influence on nuclear structure, dynamics, and astrophysics. In the introduction, we outline the historical steps leading to the concept of $$\alpha $$ α -clusterization in nuclei and provide a comprehensive description of the evolution of nuclear models capable to describe clustering aspects in nuclear systems and of the main experiments and discoveries leading to the development of this research field. We also describe some spectroscopic techniques that are used to establish the clustered nature of a given nuclear state. Some relevant experimental and theoretical findings recently reported both in experimental and theoretical works are discussed in the text. We put emphasis on recent achievements and remaining problems in the description of the structure of light isotopes, from helium to neon, including both self- and non-self-conjugate nuclei. Particular attention to the implication in the nuclear astrophysics context and to clustering effects in the dynamics of nuclear reactions is pursued all along the review.
