Abstract
By using the CHIMERA detector, we have measured the γ-ray and α decay width of excited 12C states important for the carbon production in astrophysical environments. For the first time, we directly observed the γ-ray decay of the 9.64 MeV level. A γ-ray decay width larger than previous observations was observed for the Hoyle state. In order to explain this enhanced yield we investigated on the recently proposed population of an Efimov state at 7.458 MeV. The decay characteristics of such level are inferred.
