    "abstract": "We work in a chiral invariant quark model, with a condensed vacuum,\ncharacterized by only one parameter. Bound state equations for the nucleon and\nDelta are solved in order to obtain an updated value of their radii and masses.\nNucleon-nucleon S-Wave scattering is studied in the RGM framework both for\nisospin T=1 and T=0. The phase shifts are calculated and an equivalent local\npotential, which is consistent with K-N scattering, is derived. The result is a\nreasonable microscopic short range repulsion in the nucleon-nucleon\ninteraction.",
