相对论和非相对论平均场模型中中子分布的均方半径

The mean square radius of the neutron distribution in the relativistic and non-relativistic mean field models

Haruki Kurasawa, Toshio Suzuki

摘要:

研究了非相对论平均场模型中点中子分布的均方根半径比相对论平均场模型小0.1fm的原因。这种差异是源于两种框架中的有效质量和单体势强度的乘积的不同值。这些量的值受到Hugenholtz-Van Hove定理的约束。中子皮不是对称势的简单函数,而是依赖于核子有效质量。

英文摘要:

It is investigated why the root mean square radius of the point neutron distribution is smaller by about 0.1 fm in non-relativistic mean field models than in relativistic ones. The difference is shown to stem from the different values of the product of the effective mass and the strength of the one-body potential in the two frameworks. The values of those quantities are constrained by the Hugenholtz-Van Hove theorem. The neutron skin is not a simple function of the symmetry potential, but depends on the nucleon effective mass.
