Correlations in a Many-Body Calculation of 11Li
Abstract
A many-body calculation of 11Li is presented where the only input is the well-tested, finite-range D1S effective interaction of Gogny. Pairing correlations are included in a constrained Hartree-Fock-Bogolyubov calculation, while long-range collective correlations are introduced using a GCM derived calculation. Correlations are found to play an important role in describing 11Li. A substantive underlying 9Li core of 11Li is found, which has a different density profile than a free 9Li nucleus. This may have significant implications in the use of a three-body framework in studies of 11Li.
