Isospin effects on intermediate mass fragments at intermediate energy-heavy ion collisions
文献摘要：
In this study,we investigated the isospin prop-erties of intermediate mass fragments(IMFs)for the cen-tral collisions of 112,124Sn+112,124Sn at a beam energy of 50 MeV per nucleon using an improved quantum molec-ular dynamics model(ImQMD)coupled with a sequential decay model(GEMINI).Three observables were analyzed:(1)the average center-of-mass kinetic energy per nucleonof fragments as a function of their charge number Z;(2)the average neutron number to proton number ratio(/Z)of fragments with a given charge number Z as a function of their center-of-mass kinetic energy per nucleon(Ec.m./A);and(3)the average total neutron number to total proton number ratio(Σ N/ΣZ)and double ratio(DR(N/Z))of IMFs with Z=3-8 as a function of their center-of-mass kinetic energy per nucleon Ec.m./A.Our calculations revealed that the sensitivity of the isospin properties of IMFs relative to the stiffness of the symmetry energy remains even after sequential decay.By comparing the calculations of ΣN/ΣZand DR(N/Z)with the data,it was found that the soft symmetry energy,i.e.,γ=0.5,is favored.
