Abstract
A complete version of the Moscow NN potential model is presented. The excel lent description for all essential partial waves has been found in the ener gy range 0-350 MeV. The one-channel version of the model includes the ortho gonality condition to most symmetric six-quark states in all lowest partial waves and thus, from this point of view, the model generalizes the well-kn own Saito's orthogonality condition model for the baryon-baryon interaction case. The specific features of the presented model which distinguish it fr om many conventional force models are discussed in detail. One of them is a specific tensor mixing between nodal and nodeless wave functions which res ults in very reasonable values of the one-pion exchange cutoff parameter La mbda = 0.78 GeV and the pi NN-coupling constant value f(2) = 0.075 in nice agreement with modern trends. The model, in case of its confirmation in pre cise few-nucleon calculations, can lead to noticeable revisions for many nu clear properties given by conventional force models.
