用坐标空间中的相对论Hartree-Bogoliubov理论描述了从{sup 6} Li到{sup 11} Li的锂同位素链。配对的相关性考虑到了密度依赖力的零范围。与相对论平均场理论和密度相关Hartree-Fock理论中的早期研究相反，其中{sup 11} Li中的晕只能通过接近连续极限的1 {ital p}{sub 1/2}能级的人为位移来再现，现在晕以自洽的方式再现，无需进一步修改，利用连续谱中库珀对到2 {itals}{sub 1/2}能级的散射。观察到与最近的实验数据非常一致。美国物理学会（American Physical Society）
Relativistic Hartree-Bogoliubov theory in coordinate space is used to describe the chain of lithium isotopes reaching from {sup 6}Li to {sup 11}Li. Pairing correlations are taken into account by a density dependent force of zero range. In contrast to earlier investigations within a relativistic mean field theory and a density dependent Hartree-Fock theory, where the halo in {sup 11}Li could only be reproduced by an artificial shift of the 1{ital p}{sub 1/2} level close to the continuum limit, the halo is now reproduced in a self-consistent way, without further modifications, using the scattering of Cooper pairs to the 2{ital s}{sub 1/2} level in the continuum. Excellent agreement with recent experimental data is observed. {copyright} {ital 1996 The American Physical Society.}
