Abstract
The -weighted sums (k) of the longitudinal response of two-, three-, and four-body nuclei are calculated with realistic nuclear forces, and exact (A=2) and variational (A=3 and 4) wave functions. These and the ω-weighted sums (k) are used to estimate the unmeasured longitudinal response at ω>. The Coulomb sums obtained by integrating the measured response up to ω= and the estimated response at ω>, are in good agreement with the theoretical predictions in light nuclei. The and data show the presence of proton-proton correlations, although they are not accurate enough to allow for a quantitative determination of the size of the repulsive core in the nucleon-nucleon interaction.
