Title: The Hoyle Family: break-up measurements to probe α-condensation in light nuclei

Abstract

The ^{12} 12 C Hoyle state is a candidate for \alpha α -condensation, due to its large volume and \alpha α -cluster structure. This paper discusses precision break-up measurements and how they can elucidate \alpha α -condensate structures. Two experiments are discussed in detail, firstly concerning the break-up of ^{12} 12 C and then the decays of heavier nuclei. With more theoretical input, and increasingly complex detector setups, precision break-up measurements can, in principle, provide insight into the structures of states in \alpha α -conjugate nuclei. At present, such searches have not delivered evidence for \alpha α -condensation in ^{12} 12 C or ^{16} 16 O.
