Radiative decay branching ratio of the Hoyle state

|
By M. Barbui, J. R. Bishop, G. Chubarian, V. Z. Goldberg
| Physical Review B
Background: The triple-alpha process is a vital reaction in nuclear astrophysics, characterized by two consecutive reactions [2α⇆Be8(α,γ)C12] that drive carbon formation. The second reaction occurs through the Hoyle state, a 7.65 MeV excited state in C12 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.
