Clarifying the Radiative Decay of the Hoyle State with Charged-Particle Spectroscopy

D. Dell'Aquila, I. Lombardo, L. Redigolo +33

A detailed knowledge of the decay properties of the so called Hoyle state in the ${}^{12}$C nucleus ($E_x=7.654$ MeV, $0^{+}$) is required to calculate the rate at which carbon is forg…
