Improved precision on the experimental E0 decay branching ratio of the Hoyle state

T. K. Eriksen, T. Kibédi, M. W. Reed +35

Stellar carbon synthesis occurs exclusively via the $3\hat{I}\pm$ process, in which three $\hat{I}\pm$ particles fuse to form ${}^{12}$C in the excited Hoyle state, followed by electromagnetic decay…
