To the Nature of Nuclear Force

Resumo

It has been shown for the first time that NN interaction, at least in some partial waves, can be quantitatively described by the superposition of a long-range one-pion exchange and a short-range mechanism based on the complex pole in the NN potential corresponding to the dibaryon resonance in this partial wave. For the partial waves ³P₂, ¹D₂, and ³F₃, the parameters of the complex pole that give the best description of the elastic and inelastic phase shifts of NN scattering are very close to the empirical parameters of the corresponding isovector dibaryon resonances detected experimentally. Based on the results obtained, a general conclusion is made about the nature of nuclear force at medium and small internucleon distances.
