Note on one pion exchange potential

Abstract

The phase-parameters of nucleon-nucleon scattering are worked out for the one-pion exchange potential in a way allowing localization of effects in space for each parameter. Success of phenomenologic phase-parameter fits making use of one-pion exchange values for the higher L and J is discussed in terms of the localization. It is shown that the one-pion exchange potential is probably the main interaction at distances greater than 2.9 × 10 −13 cm. With somewhat less certainty it is concluded that it is the major interaction for r > 1.6 × 10 −13, cm and evidence is presented for believing that some other interaction is the principal one for r < 1.6 × 10 −13 cm.
