Question

Definition of nucleon nucleon scattering at low energy

Answer 1

The theory developed in a previous paper (1) is here applied to the special case of high waves. The distinction between « high » and « low » waves is discussed in the text, and it is hoped that the formulae given in this paper will yield a valid representation of the nucleon-nucleon partial wave amplitudes for values of the orbital momentuml⩾2. For these high waves the cut in the energy plane due to three pion or more massive intermediate states is supposed to give a negligible contribution. In this case the representation given in I reduces to a set of explicit formulae for the partial wave amplitudes. These formulae contain explicitly the effect of the Born term and rescattering corrections in pion nucleon scattering as well as the effect of a possible pion-pion interaction.
