Abstract：
With a density-,temperature-,and momentum-dependent mean field,five diferent phases of nuclear equationo fstate:the gas,liquid,super heated liquid,supercooled gas and mechanical instability of spinodal phase for ¹⁹⁷Au are described.Afterperforming a simulation in real space and in momentum space for these diferent phases at finite temperature T=6MeV,all kinds of nuclear clusters are sorted by using the coalescence model.Correlation analysis of the nuclear clusters demonstrates that multifragmentation pattern only comes from the mechanical instability of spinodal phase.
