摘要：

A many-body calculation of Li-11 is presented where the only input is the well-tested, finite-range D1S effective interaction of Gogny. The nucleus ground state is modeled as a generator coordinate method configuration mixing of Hartree-Fock-Bogolyubov states generated with a constraint on the mean square radius. Pairing correlations are computed from the two-body interaction itself. The kinds of correlations included in this way are found to play an important role in describing the large Li-11 radius. A substantive underlying Li-9 core of Li-11 is found, which has a different density profile than a free Li-9 nucleus. The relations of this work with other approaches are discussed.
