摘要
在Hartree-Fock近似下,从扩展的Skyrme有效相互作用出发,给出了一种同位旋相关的核物质状态方程.分析了在不同相对中子过剩时的核物质状态方程.发现在核物质的饱和点处,许多物理量的同位旋相关性能够近似地与相对中子过剩满足抛物线规律.
Within the framework of Hartree-Fock approximation an isospin-dependentnuclear equation of state is obtained by using the extended Skyrme effcehve interachon.The nuclear equation of state is analyzed at different relative neutron excesses. It isfound that the binding energy increases with increment of the relative neutron excess,and the nuclear matter critical temperatUre, satUration density and the incompressbilityat saturation decrease as a function of the relative neutron excess. It is indicated thatthe properties at satUration as a function of relative neutron excess sahsfy theparabolic law.
