The ground state properties have been calculated, and momentum distributions of fragments and neutrons have been determined in a simple reaction scenario, taking into account final-state interactions. The correlation of neutrons and fragments are investigated.5 pages, 6 Postscript figures, uses REVTeXNuclear Theorytext
