摘　　要：远离β稳定线核性质研究胡济民郑春开（北京大学技术物理系，北京１００８７１）远离β稳定线核性质研究是当前核结构研究热点．理论上的研究通常是采用已有的模型和方法进行外推，当然模型的物理基础及外推的可靠性需要实验检验．我们采用了几种不同的模型与方法，对远...The microscopic method (Skyrme HF+BCS or PNC), extended Thomas Fermi method (ETF) and continuous medium model with microscopic corrections are applied to study the properties of the nuclei far from the β stability line. All light isotopes from helium to oxygen are studied with the Skyrme HF and PNC method. The experimental properties of the ground state of these nuclei are well reproduced. Some new phenomena, such as neutron skin and neutron halo, are also successfully investigated. For certain isotopic chains, the proton and neutron drip line, changes of proton and neutron density distributions, the rms radii and neutron skin thickness are studied. Some of the calculated results are compared with those of the RMF approach.
