In 1967,Fisher proposed a droplet model of a second-order phase transition to describe the power law behavior of the“fragment”mass distribution around the critical point for a liquid-gas phase transition[1].Decades later,the Purdue group generated a novel classical droplet model,which was the so-called Modified Fisher Model(MFM),based on the Fisher Model(FM)and introduced it into nuclear physics[2-4].Taking into account the basic nuclear properties,such as the Coulomb force,pairing effect,proton-neutron two-component mixture,the MFM is capable of describing the general features of the mass and isotopic yields with a minimum number of free parameters[2-4].
