Abstract

By adding isospin dependent high order correction ferms to existing relativistic mean field models．tlle thickness of neuron．skin in ²⁰⁸Pb and the radius of 1
.4 solar mass neutron star are studied．The effecfive interaction PK1 would lead the thickness of neutron-skin to a minimum of 0.17 fm which agrees with the analysis from Skyrme‘HF models． The coupling constants of the isospin dependent high order corection terms tend to change，the thickness of neutron-skin and the radius of neutron stars chan ge simultaneously.
