摘要
本文分析了小x区原子核内邻近核子间海夸克空间重叠行为,给出了核遮蔽因子R(x,Q^2,A)与空间重叠程度因子△V_Λ(x)/V_Λ(x)的关系.并据此计算了^(12)C、^(63)Cu和^(116)Sn的平均核结构函数与氘核结构函数之比,计算结果与实验数据符合甚好.
In this paper, we analyse the spatial overlapping behavior of sea quarks of neighboring nucleons in nuclei in the small x region and give a relation between the nuclear shadowing factor R(x, Q^2, A) and the spatial overlapping factor △V_Λ(x)/V_Λ(x). By using this nuclear shadowing factor R(x, Q^2, A),we calculate the ratios of the average nuclear structure functions of nuclei ^(12)C, ^(63)Cu and ^(116)Sn, to the deuteron structure function and obtais a better agreement between the calculated result and the experimental data.
