摘要:

本文在相对论平均场论框架下,在轴向形变柱坐标系中研究了$^{112-122}$ Ba核的团簇结构和团簇内部或亚结构。我们计算了总的密度分布,以及单个中子和质子的密度分布。从各种形状的密度分布的聚类配置的分析,我们发现不同的子结构的Ba核内考虑这里。第一次进行的重要步骤是对集群区域中存在的质子和中子的数量进行计数。在大多数情况下,$^{12}$ C构成Ba核的团簇构型,而$^{2,3}$ H和$^4$ He构成两个对称裂变碎片之间的颈部。

英文摘要:

We study the clustering structure and the internal or sub-structure of clusters in $^{112-122}$Ba nuclei within the framework of relativistic mean field theory in an axially deformed cylindrical co-ordinate. We calculate the total density distribution, and the individual neutrons and protons density distributions. From the analysis of the clustering confugurations of the density distributions of various shapes, we find different sub-structures inside the Ba nuclei considered here. The important step, carried out for the first time, is the counting of number of protons and neutrons present in the clustering region(s). $^{12}$C is shown to consitute the cluster configuration of Ba nuclei in most cases, with $^{2,3}$H and $^4$He constituting the neck between two fissioning symmetrical fragments.
