Present status of the long range component of the nuclear force
Abstract
In order to settle the fundamental question whether the nuclear forces involve the long range components, the Swave amplitude of the protonproton scattering is analysed in search for the extra singularity at $\nu=0$, which corresponds to the long range force. To facilitate the search, a function, which is free from the singularities in the neighborhood of $\nu=0$ when all the interactions are short range, is constructed. The calculation of such a function from the phase shift data reveals a sharp cusp at $\nu=0$ in contradiction to the meson theory of the nuclear force. The type of the extra singularity at $\nu=0$ is close to what is expected in the case of the strong van der Waals interaction. Physical meanings of the long range force in the nuclear force are discussed. Low energy pp experiments to confirm directly the strong long range interaction are also proposed, in which the characteristic interference patten of the Coulonb and the Van der Waals forces is predicted.
