          Abstract

          We present an updated version (Nijm93) of the Nijmegen soft-core potential, which gives a much better description of the np data than the older version (Nijm78). The chi^2 per datum is 1.87. The configuration-space and momentum-space versions of this potential are exactly equivalent; a unique feature among meson-theoretical potentials. We also present three new NN potential models: a non-local Reid-like Nijmegen potential (NijmI), a local version (NijmII), and an updated regularized version (Reid93) of the Reid soft-core potential. These three potentials all have a nearly optimal chi^2 per datum and can therefore be considered as alternative partial-wave analyses. All potentials contain the proper charge-dependent one-pion-exchange tail. Fortran code for the potentials can be obtained via anonymous ftp from thef-nym.sci.kun.nl
