摘要
本文在相对论平均场理论框架下,用手征对称破缺模型讨论核物质的可压缩因子,用局域的Lorentz变换和scaling坐标方法讨论了巨单极和巨四极共振激发能量。将所得结果与QHD(Quantum hadrodynamics)的σ-ω模型计算结果比较,发现可压缩因子、巨单极及巨四极态的激发能都比σ-ω模型的计算结果更加接近于实验值。
The saturating chiral breaking field theory are used to study the compressibility of the Fermi-liquid and the excitation energies of the giant monopole and quadrupole states in the framework of mean-field theory, It is found that the compressibility of the Fermi-liquid in the nuclear system, and the excitation energies of the giant monopole and quadrupole states are more close to the experimental values in comparison with the results of the σ-ω model.
