Working in a shell-model framework, we use moments of the nuclear many-body Hamiltonian to illustrate the importance of the residual interaction for accurate representations.8 pages, 4 figures; contribution to "Perspectives on Nuclear Data for the Next Decade," Bruyeres-le-Chatel, Sept 2005Nuclear Theorytext
