This review examines the tendency of light nuclei to exhibit clustering, where correlations
between nucleons result in the formation of precipitates, typically α particles. The …

Clustering has long been known to be influential in the structure of ground and excited
states of N= Z nuclei. States close to the decay thresholds are of particular interest, as …

The formed 4He (α) clusters consisting of two neutrons and two protons can be a building
block in light nuclear systems. Intriguingly, these alpha clusters could potentially form alpha …

The first excited 0+ state in C 12 (Hoyle state) has been predicted to be a dilute self-bound
gas of bosonic α particles, similar to a Bose-Einstein condensate. To clarify this conjecture …

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 …

Abstract The 7.65 MeV, J π= 0+, second excited state in 12 C is known as the Hoyle-state
after Fred Hoyle. In the 1950s Hoyle proposed the existence of the state in order to account …

Gamow–Teller (GT) transitions are the most common weak interaction processes of spin–
isospin (στ) type in atomic nuclei. They are of interest not only in nuclear physics but also in …

We study the ground and excited states of 12C employing variational calculations after spin-
parity projection in the framework of antisymmetrized molecular dynamics (AMD). The …

The nuclear structure in regions of the Segré chart which are of astrophysical importance is
reviewed. The main emphasis is put on those nuclei that are relevant for stellar …

Recent developments of physics of nuclear clustering are discussed. Our discussions are
mostly focussed on structural problems because the characteristic feature of the recent …
