“…[39]. Light 4N nuclei * Author to whom all correspondence should be addressed: ygma@sinap.ac.cn from 12 C to 28 Si were investigated in the α-clustering model of Margenau, Bloch and Brink [40]. Recently it was proposed that the giant dipole resonance [41,42] and photonuclear reaction [43,44] can be taken as useful probes of α-clustering configurations in 12 C and 16 O by some of the authors.…”

The initial geometry effect on collective flows, which are inherited from initial projectile structure, is studied in relativistic heavy-ion collisions of 12 C + Au by using a multi-phase transport model (AMPT). Elliptic flow (v2) and triangular flow (v3) which are significantly resulted from the chain and triangle structure of 12 C with three-α clusters, respectively, in central 12 C+ 197 Au collisions are compared with the flow from the Woods-Saxon distribution of nucleons in 12 C. v3/v2 is proposed as a probe to distinguish the pattern of α-clustered 12 C. This study demonstrates that the initial geometry of the collision zone inherited from nuclear structure can be explored by collective flow at the final stage in heavy-ion collisions.

“…For example, the first excited state, which has spin-parity 0 + , has been described as a four-particle-four-hole state [6], a breathing mode of the tetrahedron [7,8], or correlated with a bent rhomb [9,10]o r square [4] arrangement of α particles. The first suggestion has been put in doubt by more extensive studies [11], while the other three do not necessarily contradict each other; each model is simply too narrow in scope.…”

We calculate the low-lying spectrum of the 16 O nucleus using an α-cluster model which includes the important tetrahedral and square configurations. Our approach is motivated by the dynamics of α-particle scattering in the Skyrme model. We are able to replicate the large energy splitting that is observed between states of identical spin but opposite parities. We also provide a novel interpretation of the first excited state of 16 O and make predictions for the energies of 6 − states that have yet to be observed experimentally.

“…If the range of the potential is not greater than 1/ √ 2 α then the series in Eq. (37) converges quite fast for any value of η 2 (Brink, 1965). Therefore, only the first few terms in the series tend to be significant.…”
