N2 - It is shown that in the first-order renormalization of the two-body matrix elements in the 1s-0d shell, one must take care in the treatment of the 16O core. Explicitly, when the 16O core is treated as being unperturbed or perturbed in the complete 2hω shell-model space, the results of the renormalization are essentially the same. However, if one treats the 16O core in the Tamm-Dancoff (TDA) subspace of the 2hω model space, the results of the calculation are quite different. The origins of these effects are discussed. The renormalization of the E2 operator is also discussed.
