摘要 采用WKB方法计算在极高温度 (非共振情况 )下2 7Al(p ,α) 2 4Mg与2 7Al(p ,γ) 2 8Si两反应道分支比。在T9=(0 .0 7~ 1)温度范围内 ,R≤ 1,且在T9=(0 .0 7~ 0 .3 )范围内 ,R≤ 0 .0 2。计算表明 ,融合核反应2 7Al(p ,α) 2 4Mg可以忽略 ,Mg -Al循环是不封闭的。 The branch ratio of two fusion reactions ~~27Al(p,α)~24Mg and ~~27Al(p,γ)~28Si is calculated by the WKB method in detail in this paper under different temperatures (non-resonant). It is obtained that the branch ratio R≤1 within T 9=(0.07~1) range, and R≤0.02 within T 9=(0.07~0.3) range. It is shown that the fusion reaction ~~27Al(p,α)~24Mg can be ignored within T 9=(0.07~0.3) range, and Mg-Al cycle is unclosed.
