Interference pattern of the Coulomb and the strong Van der Waals forces in p-p scattering

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 ($T_{lab}=20\sim 30MeV.$) 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 $thet{a}_{c.m.}=14^{\circ }$ with the depth around one per cent.
