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 …

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 …

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.

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 …

What is a particle? Is it pointlike, or does it have a finite size? How does a particle exert
forces on other particles, and are these forces affected by the particle's finite size? What is …

The carbon atom provides the backbone for the complex organic chemistry composing the
building blocks of life. The physics of the carbon nucleus in its predominant isotope, 12C, is …

We propose a method for determining the nuclear radii for the excited states lying above the
particle breakup threshold based on the diffraction model of scattering. The method is …

By using only a fraction of the model space extended beyond current no-core shell-model
limits and a many-nucleon interaction with a single parameter, we gain additional insight …

The two reactions C 12 (He 4, He 4+ He 4+ He 4) He 4 and Be 9 (He 4, He 4+ He 4+ He 4) n
were measured using an array of four double-sided strip detectors. Excited states in C 12 …

The Skyrme model has two Skyrmion solutions of baryon number 12, with D 3 h and D 4 h
symmetries. The first has an equilateral triangular shape and the second an extended linear …
