Two-Nucleon Solitary Wave Exchange Potentials(SWEPs)
  A sine-Gordon solitary wave exchange NN potentials (SG SWEP) is presented as an example of a large class of realistic potentials with four or less parameters. SWEPs are derived from nonlinear quantum field theory developed by Burt. SG SWEPs resemble Reid SC potentials and they reproduce high quality phase shifts and deuteron parameters with only two parameters.
