中文摘要：

在相对论平均场的框架下，对^208Pb中子皮对新的同位旋依赖的高阶核子-ω-ρ介子耦合项的敏感性进行了研究。计算表明，高阶同位旋依赖的核子-ω-ρ介子耦合能够进一步软化对称能，因而能够在不影响其它基态可观测量的情况下，进一步减小^208Pb的中子半径。

英文摘要：

The sensitivity of the neutron skin thickness S in ^208Pb to the new addition of the high order isospin-dependent nucleon-ω-ρ coupling term in the relativistic mean field model is studied. Calculations show that the high order isospin-dependent nucleon-ω-ρ coupling term can further soften the symmetry energy, and thus further decrease the neutron radius of ^208Pb without affecting other ground-state observables.
