摘要

对\(^{106}\) Cd, \(^{102}\) Pd和\(^{104}\) Pd上的(\(\alpha ,\gamma \))反应进行了截面测量,其质心能量在\(\approx \) 7.9和11 MeV之间,位于与p过程相关的伽莫夫能量窗口内。确定的总横截面在1.4 ~ 257之间\(\mu \) b.天体物理S因子也由实验横截面导出。使用TALYS 2.0版代码进行统计模型计算,并与新数据进行比较。理论与实验总体上非常吻合。此外,还研究了核输入参数的不同组合对恒星反应速率计算的影响。

(\(\alpha , \gamma \)) cross section measurements in \(^{102}\)Pd, \(^{104}\)Pd and \(^{106}\)Cd relevant to p process

Cross-section measurements of (\(\alpha ,\gamma \)) reactions on \(^{106}\)Cd, \(^{102}\)Pd, and \(^{104}\)Pd have been performed at center-of-mass energies between \(\approx \) 7.9 and 11 MeV, which lie within the Gamow energy window relevant to the p-process. The determined total cross sections range between 1.4 and 257 \(\mu \)b. Astrophysical S factors were also derived from the experimental cross sections. Statistical model calculations were performed using version 2.0 of the TALYS code and compared with the new data. An overall very good agreement between theory and experiment was found. In addition, the effect of different combinations of nuclear input parameters entering the stellar reaction-rate calculations was investigated.
