Searching for the conditions of convergence of statistical ensembles for fragmentation of finite nuclei

The fragmentation of the nucleus into available channels (depends on phase space) can be solved in canonical and grand canonical ensembles where the underlying physical assumption is fundamentally different. In principle the results from both ensembles agree only in the thermodynamical limit when the number of particles become infinite. The aim of this work to show the results from the canonical and the grand canonical models can agree even for finite nuclei under certain conditions and to search for these conditions
