Triple Alpha Process (Helium Burning)

34He → 12C + γ

개요

Three helium-4 nuclei fuse to form carbon-12 in stars through the triple-alpha process, which occurs above 100 million K. Two helium nuclei first form unstable beryllium-8, which immediately captures a third helium to form carbon-12 via the Hoyle state resonance. Fred Hoyle predicted this resonance to explain carbon abundance.
