Abstract

The 12C Hoyle state is a candidate for α-condensation, due to its large volume and α-cluster structure. This paper discusses precision break-up measurements and how they can elucidate α-condensate structures. Two experiments are discussed in detail, firstly concerning the break-up of 12C 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 α-conjugate nuclei. At present, such searches have not delivered evidence for α-condensation in 12C or 16O.

Report

The manuscript presents a detailed discussion regarding the status of modern and sophisticated experiments aiming to investigate the structure of the 12C Hoyle state, which is a candidate for alpha-condensation. The main idea of such experiments is to measure with high precision the 3-alpha direct decay width arising from the break-up of 12C. The paper also gives an interesting overview about the theoretical models often employed to support the hypothesis that the 12C Hoyle state can be well described as a dilute gas-like state of 3 alpha particles. The paper is very well organized and several references can be found along the text. I think the manuscript is a valuable document for readers interested in the subject and therefore I recommend the publication of the manuscript in the SciPost Physics Proceedings.
