The geometrical structures and energies of mixed 38- and 55-atom Ar–Kr–Xe clusters are investigated. The interaction is described by ternary Lennard-Jones (TLJ) potential. The stable structures are optimized by adaptive immune optimization algorithm. Results show that in Ar 12 Kr m Xe n (m+n=26) clusters, there exist amorphous and polytetrahedral configurations, and in Ar ...
The putative stable structures of bimetallic Ag–Pd clusters are investigated. Gupta potential is applied to describe the interatomic interactions in Ag–Pd clusters. Experimental-fitted parameters and density-functional-theory (DFT)-fitted parameters are used to determine the lowest energy structures. Global optimization of Ag m Pd n (m+n=15) and Ag 3m Pd 38−3m...
