核物质热力学性质的扩展Skyrme力研究

Thermodynamical Properties of Nuclear Matter With Extended Skyrme Forces

从有限温度有限核的扩展Skyrme力自由能密度,熵密度和内能密度出发,计算了对称核物质和非对称核物质的一系列热力学性质,包括每核子内能、熵、核物质状态方程及不可压缩系数.

Starting from the extended Skyrme forces, free energy density, entropy density and internal energy density for finite nuclei at finite temperature are derived, from which a series of thermodynamic properties of symmetric and asymmetric nuclear matter are studied. In particalar, we analyse and discuss the nuclear equation of state (EOS) and incompressibility.
