“…Since the first heuristic proposition of α-chains as possible building blocks of even-even nuclei in the late 1960s [1], the subject of α-clustering has been a central issue in nuclear physics. It has even recently witnessed a gain of interest [2][3][4][5][6][7]. On the theoretical side, highly sophisticated ab initio calculations have shown pronounced cluster features in the ground state of a large number of light nuclei [8].…”

Abstract. Multiple alpha coincidences and correlations are studied in the reaction 12 C+ 12 C at 95 MeV for fusion-evaporation events completely detected in charge. Two specific channels with Carbon and Oxygen residues in coincidence with α−particles are addressed, which are associated with anomalously high branching ratios with respect to the predictions by Hauser-Feshbach calculations. Triple alpha emission appears kinematically compatible with a sequential emission from a highly excited Mg. The phase space distribution of α−α coincidences suggests a correlated emission from a Mg compound, leaving an Oxygen residue excited above the threshold for neutron decay. These observations indicate a preferential α emission of 24 Mg at excitation energies well above the threshold for 6 − α decay.PACS numbers: 25.70.z, 24.60.Dr, 27.30.+t, 24.10.Pa NUCLEAR REACTIONS 12C(12C,X), E = 95 AMeV, Measured Fusion-evaporation reactions, Observed deviation from statistical behaviour.

“…Furthermore, the structure of possible octupole-unstable 3:1 nuclear shapes (hyperdeformation (HD) with β 2 ≈ 1.0) has also been discussed for actinide nuclei in terms of clustering phenomena [8]. Typical examples for the link between quasimolecular bands and extremely deformed (SD/HD) shapes can be found in the literature for A = 20 − 60 α-conjugate N =Z nuclei [8,18,36,52,54,55,56,57,58,59,60,61,62,63,64,65,66,67]. Highly deformed shapes and SD rotational bands have been discovered in several light α-like nuclei, such as 36 Ar and 40 Ca by using γ-ray spectroscopy techniques [57,59].…”

Knowledge on nuclear cluster physics has increased considerably since the pioneering discovery of 12 C+ 12 C resonances half a century ago and nuclear clustering remains one of the most fruitful domains of nuclear physics, facing some of the greatest challenges and opportunities in the years ahead. The occurrence of "exotic" shapes and/or Bose-Einstein α condensates in light N =Z α-conjugate nuclei is investigated. Evolution of clustering from stability to the drip-lines examined with clustering aspects persisting in light neutron-rich nuclei is consistent with the extension of the "Ikedadiagram" to non α-conjugate nuclei.

The occurrence of "exotic" shapes in light N =Z α-like nuclei and the evolution of clustering from stability to the drip-lines are being investigated more and more accurately both theoretically and experimentally. Experimental progresses in understanding these questions were recently examined and will be further revisited in this introductory talk: clustering aspects are, in particular, discussed for light exotic nuclei with a large neutron excess such as neutron-rich Oxygen isotopes with their complete spectrocopy.
