E_d=20 keV ²H(d,γ)⁴He反应截面测量

摘要: 对E_d=20 keV的氘束入射到D-Ti靶上由²H（d,γ）⁴He反应产生的γ射线及由²H（d,p）³H反应产生的质子进行测量，得到分支比Γγ/Γp为 (1.06±0.42)×10^-7及²H（d,γ）⁴He反应截面σ的上限值为(2.9±1.2)×10^-39m²。

Abstract: The γ-ray and protons from E_d=20 keV deuterons incident on a D-Ti target were measured. The branching ratio of the ²H(d,γ)⁴He reaction versus the ²H(d,p)³H reaction is obtained to be Γγ/Γp= (1.06±0.42)×10^-7and the upper limit of the cross section of ²H(d,γ)⁴He reaction is deduced to be σ＝(2.9±1.2)×10^-39m².
