中子滴线与核物质状态方程

Neutron drip line and the equation of state of nuclear matter

Kazuhiro Oyamatsu, Kei Iida, Hiroyuki Koura

摘要:

我们调查中子滴线是如何与密度依赖的对称性能量,通过使用宏观核模型,使我们能够计算核质量的方式依赖于状态方程的非对称核物质。从这些群众得到的中子滴线示出明显转移到一个中子丰富的一方在核图表的对称性能量的密度导数的增加。这种变化在轻核中很明显,这一特征主要来自丰中子核的表面性质。

英文摘要:

We investigate how the neutron drip line is related to the density dependence of the symmetry energy, by using a macroscopic nuclear model that allows us to calculate nuclear masses in a way dependent on the equation of state of asymmetric nuclear matter. The neutron drip line obtained from these masses is shown to appreciably shift to a neutron-rich side in a nuclear chart as the density derivative of the symmetry energy increases. Such shift is clearly seen for light nuclei, a feature coming mainly from the surface property of neutron-rich nuclei.
