Abstract

In order to confirm the strong Van der Waals force in the nucleon-nucleon interaction, it is proposed to measure precisely the angular distribution of the cross section of the low energy (T_lab=20 ∼ 30MeV.) proton-proton scattering. By using the spectrum of the long range interaction obtained from the analysis of the phase shift data of the S-wave of the p-p scattering, a characteristic interference pattern, which arises from the repulsive Coulomb and the attractive strong Van der Waals forces, is predicted. The pattern has a dip at theta_c.m.=14^∘ with the depth around one per cent.
