The geometrical configuration and relative stability of the lowest-lying isomers of cadmium-doped gold clusters,Aun Cd (n =1-8)are investigated.The results obtained indicate that the lowest energy structure of Aun Cd(n =1-8)clusters is planar.The stability trend of the AunCd cluster shows an odd-even oscillation with the even numbered clusters is more stable,and indicates that Au2Cd cluster is magic one with high chemical stability.
