Two-body Correlation Contributions in Halo Nuclei in Relativistic Density Dependent Hartree Approach

摘要: 用相对论性密度依赖的 Hartree方法研究晕核的基本性质 ,在晕核的唯象图景中 ,作为剩余相互作用的对关联效应对核晕的描述有关键作用 .用只有一个自由参数的模型 ,同时给出了晕核11Li,11Be和 19C的分离能和质量密度分布 ,和实验数据符合很好. The basic properties of halo nuclei are investigated in the relativistic density dependent Hartree approach, where the correlation effects among halo particles are crucial for the description of the halo property. Adapting only one free parameter, we have calculated the separation energies and mass density distributions of halo nuclei 11 Li, 11 Be and 19 C and they are in good agreement with the experimental data.
