Abstract
The NN results are presented from the extended-soft-core (ESC) interactions. They cosist of local- and non-local-potentials due to (i) one-boson-exchange (OBE), pseudo-scalar-, vector-, scalar-, and axial-vector-nonets, (ii) diffractive exchanges, (iii) two-pseudoscalar-exchange, and (iv) meson-pair-exchange (MPE). Fits to the pp- and np-data for 0 < T(lab) < 350 MeV have typical \chi^2/Ndata= 1.15. Used are less than 20 parameters, which are coupling constants and cut-off masses. The couplings follow rather closely the pattern predicted by the quark-pair-creation model. As a result the 11 OBE-couplings are rather constrained, i.e. quasi-free. The deuteron binding energy and several NN scattering lengths are fitted at the same time.
