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.

“…Nuclear physics is developing swiftly as a result of the increased accessibility to uncommon isotopes that differ from stable nuclei in their neutron-proton ratios 3 . Hence, research on mirror nuclei provides a unique viewpoint on how coulomb interaction may affect single-particle wave functions 4 . As nuclear interactions are not reliant on the charge, similar series of excited quantum systems should exist in mirror nuclei.…”

In the context of the shell model, electromagnetic transitions were used to analyze the nuclear structure of a mirror nucleus with the same mass number, A = 13. The shell model investigation was performed by calculating the root mean square (rms) for the proton, neutron, matter and charge radii, occupancies, the excitation energies, as well as electromagnetic moments, using the elements of a body density matrix of the PSDMOD two-body effective interactions carried out in the psdpn-shell model space. The present results adopted the harmonic oscillator's single particle eigen functions and Hartree-Fock approximation. In addition, the effect of core polarization was added using the effective charge and effective g factors to calculate electromagnetic moments. To acquire a fair analysis of the information, the core polarization has to be present. The outcomes were compared with experimental data

“…Recent experimental studies of clustering in non-self-conjugate nuclei already produced exciting results, such as hints for linear chain structures stabilized by "extra" nucleons (e.g. [6][7][8]) and indications for super-radiance [9,10].…”

Background: The β-delayed proton-decay of 13 O has previously been studied, but the direct observation of β-delayed 3αp decay has not been reported.Purpose: Rare 3αp events from the decay of excited states in 13 N provide a sensitive probe of cluster configurations in 13 N.Method: To measure the low-energy products following β-delayed 3αp-decay, the TexAT Time Projection Chamber was employed using the one-at-a-time β-delayed charged-particle spectroscopy technique at the Cyclotron Institute, Texas A&M University.Results: A total of 1.9 × 10 5 13 O implantations were made inside the TexAT Time Projection Chamber. 149 3αp events were observed yielding a β-delayed 3αp branching ratio of 0.078(6)%. Conclusion:Four previously unknown α-decaying excited states were observed in 13 N at 11.3 MeV, 12.4 MeV, 13.1 MeV and 13.7 MeV and the decay modes for these states were established. We demonstrate that clustering must dominate the structure of these states to exhibit the observed decay branching ratios.
