摘要

采用半经验的Gupta多体势结合遗传算法

系统地研究了Rhn(n=3～57)团簇的几何结构特性.我们发现在铑团簇的生长中存在类fcc构型与类Ih构型之间的竞争

从n=39开始

铑团簇呈现出明显的Ih生长模式.Rhn(n=3～57)团簇的幻数为13

结合铑团簇的平均最近邻原子间距和平均配位数

分析了铑团簇幻数序列存在的原因.我们发现团簇内部原子具有增强团簇对称性和加强团簇稳定性的显著作用.

Abstract

The lowest-energy geometric structures of rhodium clusters were obtained by using a semiempirical Gupta potential combined with a global evolutive algorithm.Under this potential the most stable structures were generated up to Rh57.We found there exists structural competition between the icosahedronlike and the fcc-like.For the cases n≥39

the icosahedral growth model presents obviously.13

55 are the magic numbers of the rhodium clusters.By analyzing the average coordination number and the average nearest-neighbor distance of these clusters

we studied their magic structures.It is noticeable that the inner atoms could enhance both symmetry and stability of the clusters.
