The emission of clusters in the nuclear dissociation was investigated within the framework of isospin dependent lattice gas model.As observed in the recent experimental data,it was found that the emission probability ...
In the previous paper,a new vacuum state was defined.As claimed in that paper,this vacuum state is a thermal state in the ordinary sense.In this paper,we derive the Greens function of this vacuum and prove that it is ...
