The abundance of feed nuclei 6fe of s - process is proportional to metalicity Fe族元素作为种子核,金属丰度与[ fe h ]成正比。
S - process nucleosynthesis in agb star : the probability of a fe seed nucleus experiencing neutron irradiation 铁种子核受中子照射的概率
S - process nucleosynthesis may be a useful constraint for the evolution and convection in massive stars 过程核合成可以为大质量星的演化和对流提供有用的约束。
In this dissertation , the theory of radiative capture reaction and the s - process of nucleosynthesis of heavy element of astrophysics have been investigated 本文研究了辐射俘获反应理论和天体重元素核合成的s ?过程。
The s-process or slow-neutron-capture-process is a nucleosynthesis process that occurs at relatively low neutron density and intermediate temperature conditions in stars. Under these conditions heavier nuclei are created by neutron capture, increasing the atomic weight of the nucleus by one.
