Radiative decay branching ratio of the Hoyle state

NUCLEAR REACTIONS ¹²C(α, α'), E=40 MeV; measured reaction products, recoiled ¹²C ions, Eα, Iα; deduced radiative branching ratio of the Hoyle state. Comparison to previous experimental data. Comparison suggests to exclude the contradictory results of proton-γ-γ measurements published in 2020KI17.
