“…This approach gives an excellent description of low-density 4n nuclei such as 8 Be, the Hoyle state of 12 C, and excited states of 16 O, but was applied also to more complex nuclei such as 20 Ne 5,6,7 as well as 4n nuclei with additional nucleons 8 .…”

Quartetting (α-like clustering) occurs in low density matter (≤ 0.03 fm −3 ) which exists, e.g., at the surface of nuclei. It is of interest for the α preformation to calculate the α decay of heavy nuclei such as 212 Po, but also in light nuclei (e.g., 20 Ne) which shows strong signatures of quartetting. We analyze the intrinsic structure of the α-like cluster and the center of mass motion of the quartet, in particular the role of Pauli blocking. The Thomas-Fermi model for the (daughter) core nucleus is improved introducing quasiparticle nucleon states. Calculations performed for harmonic oscillator basis states show that the effective potential for the quartet center of mass motion remains nearly constant within the core nucleus. The relation to the THSR (Tohsaki-Horiuchi-Schuck-Röpke) approach is discussed.

“…The study of analog states in 12 C + proton and cluster states of 12 C plus two nucleons may be an interesting subject for the future. First successful investigations of 14 C have already been performed [153] employing a generalized THSR wave function. However, the more phenomenological OCM approach as applied here to 13 C also turns out to be very useful for the description of clustering.…”

In this article we review the present status of α clustering in nuclear systems. An important aspect is first of all condensation in nuclear matter. Like for pairing, quartetting in matter is at the root of similar phenomena in finite nuclei. Cluster approaches for finite nuclei are shortly recapitulated in historical order. The α container model as recently been proposed by Tohsaki-Horiuchi-Schuck-Röpke (THSR) will be outlined and the ensuing condensate aspect of the Hoyle state at 7.65 MeV in 12 C investigated in some detail. A special case will be made with respect to the very accurate reproduction of the inelastic form factor from the ground to Hoyle state with the THSR description. The extended volume will be deduced. New developments concerning excitations of the Hoyle state will be discussed. After 15 years since the proposal of the α condensation concept a critical assessment of this idea will be given. Alpha gas states in other nuclei like 16 O and 13 C will be considered. An important aspect are experimental evidences, present and future ones.The THSR wave function can also describe configurations of one α particle on top of a doubly magic core. The cases of 20 Ne and 212 Po will be investigated.

“…With the discovery of α cluster condensation in light nuclei, the Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave function has been proposed to describe gas-like cluster states in light nuclei, especially for 12 C and 16 O [8][9][10][11][12][13][14][15]. Investigations with the THSR wave function demonstrate the nonlocalized property of cluster dynamics in light nuclei such as 20 Ne [14]. In comparison with the generator coordinate method (GCM), which can be regarded as an advanced approach to the nuclear many-body problem, clustering states are found to be almost 100% accurately described by a single THSR wave function [14][15][16][17][18].…”

“…As one of the most important effects in nuclear physics, the cluster degrees of freedom have been extensively studied for various nuclear many-body problems [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15], including the microscopic description of cluster states [14,15] and cluster radioactivity such as the α decay process [4,5]. With the discovery of α cluster condensation in light nuclei, the Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave function has been proposed to describe gas-like cluster states in light nuclei, especially for 12 C and 16 O [8][9][10][11][12][13][14][15].…”

In order to study the correlations between clusters and nucleons in light nuclei, we formulate a new superposed Tohsaki-Horiuchi-Schuck-Röpke (THSR) wave function which describes both spatially large spreading and cluster-correlated dynamics of valence nucleons. Using this new THSR wave function, the binding energy of 9 B is significantly improved in comparison with our previous studies. We calculate the excited states of 9 B and obtain an energy spectrum of 9 B which is consistent with the experimental results. This includes the prediction of the first 1/2 + excited state of 9 B which is not yet fixed experimentally. We study the proton dynamics in 9 B and find that the cluster-proton correlation plays an essential role for the proton dynamics in the ground state of 9 B. Furthermore, we discuss the density distribution of the valence proton with special attention to its tail structure. Finally, the resonance nature of excited states of 9 B is illustrated comparing root-mean-square radii between the ground and excited states.
