AbstraktAbstract
We measured the y-decay probability of the Hoyle state with a new method of triple coincidence detection of a scattered a particle, a recoil 12C nucleus, and a y ray in inelastic alpha scattering on 12C. This method successfully enabled a low-background measurement and a precise determination of the y-decay probability of the Hoyle state as rya' = [4.00 +/- 0.22(sta.) +/- 0.18(sys.)] x 10-4, which is consistent with the previous literature value. Therefore, we concluded that the literature value can be reliably used in the study of nucleosynthesis in the universe.
