极高温度下^(23)Na(p,α)^(20)Ne与^(23)Na(p,γ)^(24)Mg两反应道分支比的计算

Calculation of Two Channel Branch Ratio of ^(23)Na(p,α)^(20)Ne and ^(23)Na(p,γ)^(24)Mg under Extreme High Temperature

计算在极高温度(非共振情况)下23Na(p,α)20Ne与23Na(p,γ)24Mg两反应道分支比.在(0.5～3)×108K温度下,R 10-4.表明在Ne-Na循环中,核反应23Na(p,α)20Ne可以忽略,这将有利于26Alg核素的合成.

The branch ratio of two channels ^(23)Na(p,α)^(20)Ne and ^(23)Na(p,γ)^(24)Mg under extreme high temperatures (non-resonant) is calculated.The result is R10^(-4) within \{(0.5~3)×10~8 K\}.It is shown that ^(23)Na(p,α)^(20)Ne can be ignored in Ne-Na cycle.It is beneficial to the ^(26)Al^g nucleosynthesis.
