- Аннотация: It is demonstrated that both elastic and inelastic NN scattering at laboratory energies up to 600--800 MeV, at least in some partial waves characterized by a large inelasticity, can be described by a superposition of the conventional long-range one-pion exchange and a specific short-range interaction induced by the s-channel dibaryon exchange. For the 3P2, 1D2 and 3F3 partial waves, the pole parameters giving the best fit of the real and imaginary parts of the NN phase shifts are consistent with the parameters of the respective isovector dibaryon resonances found experimentally. In the 1S0 channel, the suggested interaction gives two poles of the S-matrix -- the well-known singlet deuteron and an excited dibaryon. On the basis of the results presented, a conclusion is made about the nature of NN interaction and its strong channel dependence.
