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 …

This report addresses topics and questions of common interest in the fields of ultra-cold
gases and nuclear physics in the context of the BCS–BEC crossover. By this crossover, the …

A long-standing crucial question with atomic nuclei is whether or not α clustering occurs
there. An α particle (helium-4 nucleus) comprises two protons and two neutrons, and may be …

A review of evidence on the properties of the A= 12 nuclei, with emphasis on material
leading to information about the structure of the A= 12 systems.

The variational method complemented with the use of explicitly correlated Gaussian basis
functions is one of the most powerful approaches currently used for calculating the …

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 …

The excited state of the C 12 nucleus known as the “Hoyle state” constitutes one of the most
interesting, difficult, and timely challenges in nuclear physics, as it plays a key role in the …

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 …

The Hoyle state plays a crucial role in the helium burning of stars heavier than our Sun and
in the production of carbon and other elements necessary for life. This excited state of the …

We report a measurement of a new high spin J π= 5− state at 22.4 (2) MeV in C 12 which fits
very well to the predicted (ground state) rotational band of an oblate equilateral triangular …
