摘要：

We determine the Coulomb sum for He-4 using the world data on He-4(e,e') and compare the results to calculations based on realistic interactions and including two-body components in the nuclear charge operator. We find good agreement between theory and experiment when using free-nucleon form factors. The apparent reduction of the in-medium G(Ep) implied by IA-interpretation of the L/T-ratios measured in He-4(e,e'p) and He-4((e) over right arrow ,e'(p) over right arrow) is not confirmed.
