摘要Thermal properties of asymmetric nuclear matter, including the temperature dependence of the symmetry energy, single-particle properties, and differential isospin fractionation, are investigated with different neutronproton effective mass splittings by using an improved isospin- and momentum-dependent interaction. In this improved interaction, the momentum dependence of the isoscalar single-particle potential at saturation density is well fit to that extracted from optical-model analyses of proton-nucleus scattering data up to the nucleon kinetic energy of 1 GeV, and the isovector properties, i.e., the slope of the nuclear symmetry energy, the momentum dependence of the symmetry potential, and the symmetry energy at saturation density, can be flexibly adjusted via three parameters: x, y, and z, respectively. Our results indicate that the nucleon phase-space distribution in equilibrium, the temperature dependence of the symmetry energy, and the differential isospin fractionation can be significantly affected by the isospin splitting of the nucleon effective mass.
