Abstract

Thermodynamical behavior of(AgBr)n(n=7-9) clusters were studied by using constant temperature molecular dynamics.The result showed that the structure of(AgBr)9 was seriously distorted,the face and flank of the structure were exchanged for(AgBr)7,but the profiles of ground structures for them unchanged within the range of middle temperature.For(AgBr)8 cluster,the stable structure transformed into a cage composed of two eight-ring at 160 K,the face and flank also exchanged at temperature of 160-360 K.
