The astrophysical S-factor for proton capture on 9Be at astrophysical is considered in this work by using a modified potential model approach. The total cross-section is taken as the sum of both direct and resonance transitions. Based on the computed total astrophysical S-factor we calculate the nuclear reaction rates within the selected range of temperatures. The calculated values of S-factor and nuclear reaction rates are in good agreement with the measured data. Our modified potential model based astrophysical S-factor at zero energy shows a satisfactory agreement with the previously published results.

重新检查质子俘获的天体S因子 在恒星方面
天体物理学S因子质子捕获于9在天体物理铍在这项工作中,通过使用改进的潜在模型方法考虑。总横截面取为直接和共振跃迁的总和。基于计算出的总天体S因子,我们计算出所选温度范围内的核反应速率。S因子和核反应速率的计算值与实测数据非常吻合。我们基于零能量的天体物理S因子的改进的势能模型显示了与先前发表的结果令人满意的一致性。
