Abstract

The rate of neutron-induced nucleosynthesis of heavy nuclei is determined by the astrophysical scenario and by the rate of beta decay of nuclei involved in the r-process. The effect of beta-decay rates calculated within various theoretical models on the abundances of heavy nuclei is analyzed on the basis of the yields of heavy nuclei in the r-process and the determination of their sensitivity to input data. It is shown that a sizable change in the r-process rate has a strong effect on the process of formation of the third peak in the abundance curve and on the size and position of this peak.

r过程中产生的核丰度的核合成速率依赖性

摘要

中子诱发重核的核合成速率取决于天体物理情况以及参与r过程的核β衰变速率。根据r过程中重核的产率及其对输入数据敏感性的确定，分析了在各种理论模型中计算出的β衰变速率对重核丰度的影响。结果表明，r处理速率的较大变化对丰度曲线中第三个峰的形成过程以及该峰的大小和位置都有很大影响。
