Nuclear reactions induced by photons play a vital role for very different aspects of basic
research and applications in physics. They are a key ingredient for the synthesis of nuclei in …

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 …

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.

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 …

This review discusses the main achievements and future perspectives of the MAGNEX
spectrometer at the INFN-LNS laboratory in Catania (Italy). MAGNEX is a large-acceptance …

The second J π= 2+ state of C 12, predicted over 50 years ago as an excitation of the Hoyle
state, has been unambiguously identified using the C 12 (γ, α 0) Be 8 reaction. The alpha …

We derive the rotation-vibration spectrum of a 4 α configuration with tetrahedral symmetry T
d and show evidence for the occurrence of this symmetry in the low-lying spectrum of O 16 …

We investigate the α+ O 16 cluster structure in the inversion-doublet band (K π= 0 1±) states
of Ne 20 with an angular-momentum-projected version of the Tohsaki-Horiuchi-Schuck …

We present a review of recent works on clustering phenomena in unstable nuclei studied by
antisymmetrized molecular dynamics (AMD). The AMD studies in these decades have …

Background: Near-threshold α-clustered states in light nuclei have been postulated to have
a structure consisting of a diffuse gas of α particles which condense into the 0 s orbital …
