相对论hartree近似下的不可压缩因子

Incompressibility Coefficient in the Relativistic Mean Field Hartree Approximation

本文在平均场理论框架下。用手征对称破缺模型讨论了原子核的不可压缩因子,确定了手征破缺模型满足核物质饱和性的耦合参数。将所得到的结果与walecka的σ-ω模型比较,发现不可压缩因子有所压低,较σ-ω模型更加接近实验值。

By using the chiral-symmtry-breaking model, the incompressibility coefficient of nuclear system are discussed within the framework of relativistic mean field, and the couping constant of chiral-symmtry-breaking which can satisfy the saturation of nuclear system are determined. It is found that the incompressibility coefficient is more close to the experimental value in comparision with the result of the σ-ω model of Walecka.
