有限核物质的饱和性质与液气相变

ON THE SATURATION PROPERTIES AND THE LIQUID-GAS TRANSITION OF FINITE NUCLEAR MATTER

在核物质Hartree-Fock理论框架下,应用SKM~*,SKb和SGⅡ三种Skyrme等效核力参数与带屏蔽的二体库仑势,顾及到核的有限尺度效应,得到了合理的有限核零温饱和性质,发现有限核物质的液气相变临界温度约为12MeV,比无限对称核物质的约低2—3MeV。

The saturation properties and the liquid-gas transition of finite nuclear matter are investigated with the Skyrme effective interaction and the Coulomb interaction in the framework of Hartree-Fock theory. The critical temperature for liquid-gas transition of finite nuclear matter is found to be around 12 MeV.
