核子-核子相互作用力是描述原子核体系的基础。随着大量极端条件下,特别是大量丰中子核实验新数据的出现，已有的唯象有效核力模型在描述这些新的实验结果面临极大挑战，澄清同位旋不对称核介质中对称势和核子质量劈裂的效应是其关键之一。本项目拟采用Skyrme-Hartree-Fock方法，通过现有的核结构实验数据，特别是远离beta稳定线核的新的实验数据，建立两个系列的Skyrme核子-核子有效相互作用参数组，分别研究对称势和核子有效质量劈裂效应。将其应用于动力学及热力学模型，一方面可以通过中能重离子反应、核物质液气相变等研究非对称核物质核态方程，特别是对称能的密度和温度依赖关系、介质内核子有效质量劈裂行为等，另一方面可以利用实验数据检验和约束我们所建立起来的Skyrme参数并寻找有效质量敏感观测量。

The nucleon-nucleon interaction is the fundation of the nuclear theory in description of nuclear system. With the appearance of more and more experimental data of nuclear structure and reactions under the extream conditions, it is a great challenge for present phenomenological effective nucleon-nucleon interaction models to understand the new nuclear phenomena. The effects of symmetry potential and the mass splitting in isospin asymmetric metter play the key role for understanding these phenomena. With the Skyrme-Hartree-Fock method and the existing experimental data of nuclear structure, especially the new data about the nuclei far from beta stability line, we plan to constructe two series of Skyrme effective nucleon-nucleon interactions parameter sets, in order to investigate the effects of symmetry potential and nucleon effective mass splitting. The new Skyrme parameter sets will be applied in the nuclear dynamical models and thermodynamic models for two motivations: Firstly, to investigate the equation of state for asymmetric nuclear matter, especially the density and temperature denpendence of symmetry energy, and the behaviors of in-medium nucleon effective mass splitting etc. Secondly, to test and constrain the Skyrme parameter sets with the experimental data and seeking the sensitive observables for effective mass splitting.
