    "abstract": "We calculate S-wave singlet and triplet NN phase shifts stemming from the\nshort-range flavor-spin hyperfine interaction between constituent quarks using\nthe resonating group method approach. A strong short-range repulsion is found\nin both waves. A fair comparison is performed between the traditional picture,\nrelying on the colour-magnetic interaction, and the present one, relying on the\nGoldstone boson exchange dynamics. It is shown that the latter one induces\nessentially stronger repulsion, which is a very welcome feature. We also study\na sensitivity of phase shifts and wave function to extention from the\none-channel to three-channel resonating group method approximation.",
