摘要
利用贫金属星中子俘获元素丰度的模型计算了 30颗样品星的分量系数 ,并详细分析了弱 s过程分量系数 C2
Using the model of determining the relative contributions from different nucleosynthesis processes to the abundances of the heavy elements in metal poor stars,we calculate the component coefficients of 30 sample stars.The results show that the weak s process component coefficiewt C 2 is below zero in some sample,we sugget some possible reasons to explain this phenomenon.
