摘要
运用相对论平均场理论结合Wigner-Seitz近似,研究了致密物质中电子气体对56Fe和120Sr结构的影响,对关联的处理采用Bardeen-Cooper-Schrieffer方法.结果表明电子气体对单粒子能级、核子密度分布、核子分布均方根半径、原子核均方根半径等性质都有影响,并且对质子的影响大于对中子的影响.
The influence of electron gas on atomic nuclei ^56Fe and ^120Sr in compact matter has been studied by relativistic mean field theory in combination with Wigner-Seitz approximation.Bardeen-Cooper-Schrieffer approximation is used to deal with pairing correlations.The results show that single-particle energy levels,nucleon density distributions and root-mean-square radii are changed due to electron gas.The influence on protons is greater than that on neutrons.
