Precise measurement of the <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" altimg="si10.svg"> <mml:mi>γ</mml:mi> </mml:math> -decay probability of the Hoyle state with a new triple coincidence-detection method
We measured the γ-decay probability of the Hoyle state with a new method of triple coincidence detection of a scattered α particle, a recoil 12C nucleus, and a γ ray in inelastic alpha scattering on 12C. This method successfully enabled a low-background measurement and a precise determination of the γ-decay probability of the Hoyle state as Γγ/Γ=[4.00±0.22(sta.)±0.18(sys.)]×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.
