Abstract：
Using a phenomenological asymmetric nuclear equation of state, we obtained pressure-density isotherms of the finite nucleus ¹¹²Sn simulated in r-space and in p-space and constructed the nuclear fragments by using the coalescence model. After correlatively analysing the fragments, the signal of critical behavior has been found and critical exponents were also extracted.
