Abstract

Relativistic Hartree-Bogoliubov theory in coordinate space is used to describe the chain of lithium isotopes reaching from 6Li to 11Li. 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 11Li could only be reproduced by an artificial shift of the 1p1/2 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 2s1/2 level in the continuum. Excellent agreement with recent experimental data is observed.
