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.}
