S. Misicu, F. Carstoiu

摘要:

在一个标准的方法融合的碳和氧的燃烧周期在高度演化的恒星相关的融合反应进行了研究。我们采用双折叠方法计算Gogny-D1和M3 Y-Paris $n-n$有效力下的离子-离子相互作用。横截面的评估没有表明可能的障碍,即使在最低的能量下的障碍。反应速率在温度相关的恒星过程的估计和比较,传统的和现代的外推公式。

英文摘要:

Fusion reactions relevant for the carbon and oxygen burning cycles in highly evolved stars are investigated in a standard approach to fusion. We employ the double folding method to evaluate the ion-ion interactions with Gogny-D1 and M3Y-Paris $n-n$ effective forces. The cross-section evaluation do not indicate a possible hindrance even at the lowest energies under the barrier. Reaction rates at temperatures relevant for the stellar processes are estimated and compared to the traditional and modern extrapolation formulas.
