High precision proton angular distribution measurements of ${}^{12}$C(p,p') for determination of the $E0$ decay branching ratio of the Hoyle state

K. J. Cook, A. Chevis, T. K. Eriksen +14

Background: In stars, carbon is produced exclusively via the $3\alpha$ process, where three $\alpha$ particles fuse to form ${}^{12}$C in the excited Hoyle state, which can then decay to the g…
