| In order to obtain new information on the NN-interaction, the energy-weighted longitudinal sum rule for electron-nucleus scattering is studied. Simple formulas for calculating the sum rule for a NN-force of general structure are derived. The sum-rule calculation is reduced, in the general case, to calculating a quantity of the < V > type with the V NN -interaction components being algebraic combinations of the components of the true NN-interaction. Results of the sum rule calculation in the A = 3 case using some realistic and model NN-forces are presented and discussed. It is noted that the determination of appropriate experimental sums for 3He, 3H may allow a new test of the NN-interaction to be made. The possibility of simplifying VCoul operators in some calculations is also noted. |
