摘要
本文研究了部分子在核环境中的演化对束缚核子结构函数的影响,并结合小x区域核内邻近核子间部分子空间重叠引起的核遮蔽效应,计算了原子核^(56)Fe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。
The effect of the evolution of partons in nuclear environment to the structure function of
nucleons bound in a nucleus is investigated. Together with the nuclear shadowing effect caused
by the spatial overlap of partons from neighboring nucleons in the nucleus in the small x
region, the ratio of the average nuclear structure function of nucleus ^(56)Fe to the deuteron struc-
ture function is calculated and a good agreement between the calculated results and the ex-
perimental data is obtained.
