A model suggested by Sudarshan which relates strong, weak, and electromagnetic interactions through vector and axial-vector currents is adapted to nucleon-nucleon scattering. Strong time-reversal violation is predicted in n-p scattering above 100 MeV through the same mechanism assumed to cause CP-invariance violation in weak hadronic decays. Where a T-invariance violation has been sought for and not found, i.e., in p-p scattering up to 635 MeV and low-energy n-p scattering, the model predicts very little T-invariance violation.
