核物质参数耦合模型的同位旋约束

Isospin Constraints on the Parametric Coupling Model for Nuclear Matter

Guilherme F. Marranghello, Constança Providência, Alexandre M. S. Santos

摘要:

利用同位旋约束研究了非对称核物质的参量耦合模型和性质。除了通常的核物质约束--有效核子质量和饱和密度下的不可压缩性--和中子星约束--最大质量和半径--我们还研究了与对称能有关的性质。这些性质将模型的参数限制在一个很小的范围内。我们将所得结果应用于研究液-气相变和中子星组态的热力学不稳定性。

英文摘要:

We make use of isospin constraints to study the parametric coupling model and the properties of asymmetric nuclear matter. Besides the usual constraints for nuclear matter - effective nucleon mass and the incompressibility at saturation density - and the neutron star constraints - maximum mass and radius - we have studied the properties related with the symmetry energy. These properties have constrained to a small range the parameters of the model. We have applied our results to study the thermodynamic instabilities in the liquid-gas phase transition as well as the neutron star configurations.
