Description
Zhou and co-authors report evidence for a gas-like state of five alpha particles inside a neon nucleus. Alpha particles, each made of two protons and two neutrons, can cluster inside light nuclei. In carbon-12, three of them form the famous Hoyle state, a loose condensate that lets stars forge carbon. Whether bigger nuclei hold matching states has stayed an open challenge.
Running microscopic five-body calculations for neon-20, the team finds one excited state with the loose, gas-like character of a condensate of all five alphas. They present it as the five-alpha counterpart of the Hoyle state. Confirming such states, they argue, would firm up the whole idea of alpha condensation in nuclei.
