“…The Alpha Cluster Model proposed by Brink et al [68] as an extension of the old work by Margenau [46], was subsequently used to describe the cluster structure of several self-conjugate nuclei (see, e.g., [65,69]). Another mathematical model for clustering, developed by Yuri Smirnov and collaborators in Moscow, allowed the calculation of electric transitions strengths Eλ; from the comparison with experimental data, a large degree of α clustering in 9 Be was seen, with an isolation extent of α clusters well larger than the one typically predictable by shell model calculations [70].…”

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.

“…It has been found that the isolation parameter has different values for nuclei with cluster structure. For instance, = 0 5÷0 6 for 9 Be, = 0 7 for 12 C and = 0 8 for 16 O [27,28]. The elastic scattering charge form factor, although sensitive to the value of , can be described by different models due to the fact that it is obtained on the basis of the charge density distribution that is averaged over the angular variables.…”

Abstract:The charge form factor of the 6 Li nucleus is considered on the basis of its cluster structure. The charge density of 6 Li is presented as a superposition of two terms. One of them is a folded density and the second one is a sum of the 4 He and deuteron densities. Using the available experimental data for 4 He and deuteron charge form factors, a satisfactory agreement of the calculations within the suggested scheme is obtained with the experimental data for the charge form factor of 6 Li, including those in the region of large transferred momenta.
