讨论了目前16O(α ,γ) 2 0 Ne反应的实验研究工作 ,并对2 0 Na β+—→2 0 N →16O +α的β+ 缓发衰变α能谱的相对强度值同文献进行了比较 ,讨论了低能激发能级、共振强度及其对共振截面的贡献、S因子的理论研究 . The current experimental work on 16O (α, γ) 2 0 Ne reaction is discussed. The relative intensity values ​​of β + slow decay α-energy spectrum of 20 Na 2 + - → 2 0 N → 16O + α are discussed in the literature In comparison, the theoretical study on the S-factor of the low-level excitation energy level, the resonance intensity and its contribution to the resonance cross-section is discussed.
