Abstract
A microscopic NN potential is presented where the annihilation contribution is described by the quark rearrangement model and the one-boson-exchange contribution is further added. Gross features of PP scattering observables are described by the potential with modification by a phenomenological repulsion at short distances. The NN potential has the remarkable features: the strong dependence on energy and quantum-numbers, the node effects and the tensor-force dominance. These properties create several narrow-width bound and resonance states in the mass region 1900\gtrsimMNN≳1360 MeV. The nature of the phenomenological repulsion is discussed.
