恒星增强因子和~（85）Rb（p，n）~（85）Sr反应的抑制
Suppression of the stellar enhancement factor and the reaction 85Rb(p,n)85Sr
摘要：
结果表明，库仑抑制的恒星增强因子发生在许多吸热反应和远离稳定。与通常的假设相反，尽管它们的负反应Q值，但对恒星增强影响最小的天体物理学反应测量应该优选地对这些反应而不是它们的反向反应进行。作为示范，通过在2.16<= E_{c.m.} <= 3.96 MeV之间的活化测量了与天体物理学相关的85 Rb（p，n）85 Sr反应的截面，并且从数据直接推断出（p，n）以及（n，p）在p过程温度下的天体物理学反应速率。此外，我们的研究结果证实了先前推导的修改的全球光学质子势。所提出的参数也是相关的其他α和质子诱导的反应中的p-，rp-和nu-p-过程。
英文摘要：
It is shown that a Coulomb suppression of the stellar enhancement factor occurs in many endothermic reactions at and far from stability. Contrary to common assumptions, reaction measurements for astrophysics with minimal impact of stellar enhancement should be preferably performed for those reactions instead of their reverses, despite of their negative reaction Q-value. As a demonstration, the cross section of the astrophysically relevant 85Rb(p,n)85Sr reaction has been measured by activation between 2.16<=E_{c.m.}<= 3.96 MeV and the astrophysical reaction rates at p-process temperatures for (p,n) as well as (n,p) are directly inferred from the data. Additionally, our results confirm a previously derived modification of a global optical proton potential. The presented arguments are also relevant for other alpha- and proton-induced reactions in the p-, rp-, and nu-p-processes.
