“…Moreover, the strong influence of cluster structures on the appearance of superdeformed bands is emphasized. It should be noted that a similar result is found, theoretically, in the case of 32 S, where 16 O + 16 O cluster states are important in the AMD calculations of superdeformed 32 S states [52].…”

“…The cluster structure of the nucleus 20 Ne has often been cited as the best example of clustering in light nuclei (e.g. [31,32]). This is not, perhaps, surprising given that two closed shell nuclei are involved-the α cluster resides outside the 16 O core.…”

“…a priori no clustering). From the experimental perspective the level structure of 16 O+α states in 20 Ne has been characterized in terms of bands by both Bromley [32] and Tomoda and Arima [37]. These states have very large α-reduced widths which clearly mark out their cluster parentage [38].…”

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 was suggested that these extremely-deformed minima corresponded to shapes with axes in the ratio of simple integers analogous to, the then known, fissioning shape isomers in very heavy nuclei and, subsequently discovered a decade later, superdeformed nuclei. The possible connection to the 12 C + 12 C molecular resonances was also made at this time (Bromley 1975).…”

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.

“…This transfer could proceed to the sd-shell, populating cluster states above the α-decay threshold at 4.01 MeV. States populated in this manner would naturally be expected to have a t + 16 O type cluster structure, and be possible analogues of the well-known α + 16 O clusters states in 20 Ne [11,12]. States which strongly α-decay would require a 1p-1h excitation of the 16 O core, with a proton being excited to the sd-shell.…”

A search for the α + 6 He decay of 10 Be has been performed using the Li 2 O( 18 O,α 6 He) reaction at 80 and 100 MeV. An array of two Si-Si-CsI telescopes was used for the coincident detection of the breakup fragments. No evidence for the 16 O( 18 O,α 6 He) 24 Mg reaction was obtained, the cross-section being determined as σ < 1.9 μb and <3.9 μb at 80 and 100 MeV, respectively. The α + 15 N decay of 19 F was observed via the 7 Li( 18 O,α 15 N) 6 He reaction. For the 19 F excitation energy and centre-of-mass scattering angle ranges covered, the cross-sections are σ = (31.7 ± 6.6) μb at 80 MeV and (31.8 ± 6.6) μb at 100 MeV.
