Abstract：
With a density-, temperature-, and momentum-dependent mean field, five different phases of nuclear equation of states (gas, liquid, super-heated liquid, super-cooled gas, and mechanical instability of the spinodal phase) for ¹⁹⁷Au are described. After performing a simulation in coordinate space and in momentum space for these different phases at finite temperature T=6 MeV, all kinds of nuclear clusters are sorted by using the coalescence model. The correlation analysis of the nuclear clusters demonstrates that the muitifragmentation pattern only conies from the mechanical instability of the spinodal phase.
