Studying the space structure of NN interaction

The potential of the NN interaction Vsub(NN) is constructed with the account of coupling between the NN and the six-quark components of the wave function. To describe the NN interaction the collective variable rhosup(2) is used which is proportional to the sum of the quarks distances from the 6sub(q) centre-of-mass squared. Potential Vsub(NN) at rho → infinity coincides with the one-exchange potential. At rho → 0 potential Vsub(NN) increases as the energy of quarks localized in a small volume grows; this increase of the quark energy manifests itself as a repulsion in the 6q-system. The combined action of the repulsion at small rho and the confinement forces results in the transition nucleons 6q-bag occuring only in the narrow range around rho approximately equal to 1.5 fm. The constructed potential provides good description of the scattering lengths, effective radii and S-wave NN scattering phase shifts in the energy range of Tsub(lab) approximately equal to 600-800 MeV
