“…Combining OCM and GEM provides a powerful tool to study the structure of light nuclei [21,38,44,46] as well as light hypernuclei [4,70], because the Pauli-blocking effect among the clusters is properly taken into account and GEM covers an approximately complete model space [68,69]. It is also useful to apply Kukulin's method [71] for removing the Pauli-forbidden states u F 's from the wave function Φ (OCM) nα . The present OCM-GEM framework, for example, in the case of 16 O, can cover a model space large enough to describe the dilute α gas-like configuration, as well as α + 12 C cluster and shell-model-like ground state structures.…”

The α-particle condensate in nuclei is a novel state described by a product state of α's, all with their c.o.m. in the lowest 0S orbit. We demonstrate that a typical α-particle condensate is the Hoyle state (E x = 7.65 MeV, 0 + 2 state in 12 C), which plays a crucial role for the synthesis of 12 C in the universe. The influence of antisymmentrization in the Hoyle state on the bosonic character of the α particle is discussed in detail. It is shown to be weak. The bosonic aspects in the Hoyle state, therefore, are predominant. It is conjectured that α-particle condensate states also exist in heavier nα nuclei, like 16 T. Yamada, Y. Funaki, H. Horiuchi, G. Röpke, P. Schuck, and A. Tohsaki particle condensation in finite nuclei to quartetting in symmetric nuclear matter is investigated with the help of an in-medium modified four-nucleon equation. A nonlinear order parameter equation for quartet condensation is derived and solved for α particle condensation in infinite nuclear matter. The strong qualitative difference with the pairing case is pointed out.

“…This value is larger than C = 2.3 fm −1/2 extracted from the elastic α-d 3 S 1 experimental phase shift by the analytic extrapolation to the pole of the partial scattering amplitude corresponding to the 6 Li ground state [35]. The same value of the ANC was also obtained from the solution of the three body α-p-n equation [36], which was used in Refs. [33,34] and confirmed recently by ab initio calculations [37].…”

Abstract.Within the potential cluster model with the forbidden states and an orbital states classification according to the Young diagrams the possibility of description of experimental data for the total cross-sections of radiative n 15 N-capture at energies from 25 to 370 keV was considered. It was shown that only on basis of the E1-transitions from the different states of n 15 N-scattering to the ground state of 16 N nucleus in n 15 N-channel it is well succeed to explain the value of the total cross-sections in the considered energy range and to prognosticate its behavior at energy E  1 eV. These cross-sections at energies E  10 keV are approximated by the simple analytical form.
