英文摘要: The shear viscosity of hot nuclear matter is investigated by using the mean free path method within the framework of the isospin-dependent quantum molecular dynamics model. Finite size nuclear sources at different density and temperature are initialized based on the Fermi-Dirac distribution. The results show that shear viscosity to entropy density ratio decreases with the increase of temperature and tends toward a constant value for rho similar to rho(0), which is consistent with the previous studies on nuclear matter formed during heavy-ion collisions. At rho similar to 1/2 rho(0), a minimum of eta/s is seen at around T = 10 MeV and a maximum of the multiplicity of intermediate mass fragment (M-IMF) is also observed at the same temperature which is an indication of the liquid-gas phase transition.
