High-precision proton angular distribution measurements of C12(p,p) for the determination of the

Abstract: Background: In stellar environments, carbon is produced exclusively via the 3α process, where three α particles fuse to form 12 C in the excited Hoyle state, which can then decay to the ground state. The rate of carbon production in stars depends on the radiative width of the Hoyle state. While not directly measurable, the radiative width can be deduced by combining three separately measured quantities, one of which is the E 0 decay branching ratio. The E 0 branching ratio can be measured by exciting the Hoyle… Show more

“…More recently, Freer & Fynbo (2014) have performed an up-to-date review of the relevant literature to affirm the recommended value as Γ rad = 3.7 meV. Recent measurements by Eriksen et al (2020), Kibedi et al (2020), andCook et al (2021) have proposed a revised width of Γ rad = 5.1(6) meV. If true, this would imply an upward revision in the 3α rate at the 37.8% level.…”

“…Helium burning is triggered by the 3α process releasing 7.5 MeV in fusion energy and producing 12 C (Hoyle 1954;Eriksen et al 2020;Kibédi et al 2020;Cook et al 2021). This is a unique process, setting stringent conditions for helium ignition.…”
