Density fluctuations in intermediate-energy heavy-ion collisions
文献摘要：
Within the framework of the isospin-dependent quantum molecular dynamics model,we simulate 129Xe+119Sn collisions in an incident energy range of 20 to 190 MeV/nucleon and discuss the liquid-gas phase transition with density fluctuations.For comparison,we also extract the effective Fisher parameter τeff,multiplicity of inter-mediate-mass fragments(IMFs),and information entropy.It is found that the Fisher parameter and maximum infor-mation entropy of collisions have peak values at Ebeam=50-80 MeV/nucleon.In addition,the maximum multiplicity of IMFs has a plateau around 70 MeV/nu-cleon.For higher-order density moments in a larger central region of[-5,5]3 fm3 in the collision system,a maximum plateau also appears as function of beam energy at energies exceeding 70 MeV/nucleon.These observables,which are consistent with each other,indicate a liquid-gas phase transition around 70 MeV/nucleon for the 129Xe+119Sn system.
