The triple-alpha process is a vital reaction in nuclear astrophysics, characterized by two consecutive reactions 2α ⇌ 8Be (α, γ) 12C that drive carbon formation. The second reaction occurs through the Hoyle state, a 7.65 MeV excited state in 12C with Jπ = 0+. The rate of the process depends on the radiative width, which can be determined by measuring the branching ratio for electromagnetic decay. Recent measurements by Kibédi et al. conflicted with the adopted value and resulted in a significant increase of nearly 50% in this branching ratio, directly affecting the triple-alpha reaction. Here, this work aims to utilize charged-particle spectroscopy with magnetic selection as a means to accurately measure the total radiative branching ratio (Γrad/Γ) of the Hoyle state in 12C.
