I am looking for the most precise currently available deuterium potential energy curve (generated purely by experimental data) on the nucleon-nucleon scale. This is crucial. I need a radial cross-section from experiment, not theory. Would someone who is experienced in resourcefulness please direct me to an original, highly precise and accurate (and credible) source that is up-to-date?
Either the Nijmegen or Argonne v18 potentials are "realistic," meaning that they fit the two-body (pp,np) scattering data up to 350 MeV lab with $\chi^2$ per datum ~ 1. Using their names you can search online and the literature.
