“…This showed that the region of the excitation energy spectrum associated with the 4 + states is further fragmented into a finer structure. These narrower resonances correlated well with the, so-called, barrier resonances observed in reactions proceeding from the 12 C + 12 C entrance channel [145,146], reinforcing the idea of a common origin.…”

The subject of clustering has a lineage which runs throughout the history of nuclear physics. Its attraction is the simplification of the often uncorrelated behaviour of independent particles to organized and coherent quasi-crystalline structures. In this review the ideas behind the development of clustering in light nuclei are investigated, mostly from the stand-point of the harmonic oscillator framework. This allows a unifying description of alpha-conjugate and neutron-rich nuclei, alike. More sophisticated models of clusters are explored, such as antisymmetrized molecular dynamics. A number of contemporary topics in clustering are touched upon; the 3α-cluster state in 12 C, nuclear molecules and clustering at the drip-line. Finally, an understanding of the 12 C + 12 C resonances in 24 Mg, within the framework of the theoretical ideas developed in the review, is presented.

“…It is clear that many of the structures which had been assumed to be broad states are in fact fragmented into a series of much narrower states with widths ∼100-150 keV, consistent with statistical expectations. However, the increased resolution also permitted a detailed comparison to be made between the breakup states and quasimolecular resonances observed in the 12 C + 12 C total reaction cross section [62,63]. There appears to be reasonable agreement between the two sets of data in terms of the energies, spins and widths, indicating a common structural link.…”

We review some of the developments in the experimental and theoretical understanding of cluster symmetries. We pay particular attention to the association of clustering with highly deformed configurations and to the ways in which the symmetries of the nuclear interaction give rise to many different cluster modes. On the experimental side we concentrate particularly on those experimental studies of clustering where resonant particle spectroscopy is applied to breakup reactions, using position-sensitive, charged-particle detectors. We investigate the role of clustering and cluster models in nuclear reactions and examine the recent evidence for -cluster chain configurations in the light even - even nuclei from to . On the theoretical side, we briefly introduce fully microscopic models, but concentrate mainly on Bloch - Brink and local potential cluster models. The double-resonance mechanism, band-crossing model and recent work on explicit models of the interaction between deformed nuclei are also summarized.

“…Of particular interest were reaction channels leading to final states such as 12 C( 12 C, α) 20 Ne or 12 C( 12 C, p) 23 Na. Galster et al (1977) and Voit et al (1977) reported detailed excitation-function data for the 12 C( 12 C, α) reaction populating several levels in 20 Ne, spanning centre-of-mass energies between 4 and 13 MeV. Many resonances were observed, and by measuring the angular distribution of transitions to either 0 + or 2 − final states (see section 2.5), spins were assigned to 11 of these resonances.…”

We review the subject of nuclear molecular states as exemplified by the experimental observations of narrow resonances in the scattering and reactions of heavy ions. These states are at high excitation energy and sometimes high angular momentum and have very large partial decay widths into symmetric and near symmetric partitions. The experimental data accumulated over the past 30 years are summarized and various theoretical models discussed.
