Recent nucleon-nucleon scattering data and the Paris potential predictions

New data (cross section, polarization, Wolfenstein parameters, and spin-correlations) on proton-proton and neutron-proton scattering have been recently published by differenc groups. These include high precision and/or original measurements covering the energy range $6 \mathrm{MeV}<T_{\mathrm{lab}}<800\mathrm{} \mathrm{MeV}$. A direct comparison of these data with the values produced by the Paris $\mathrm{NN}$ potential for energies $T_{\mathrm{lab}}<350\mathrm{}$ MeV is reported here. The agreement between theory and experiment is very satisfactory both for low and medium energies. The total ${\chi }^2$ for the world $\mathrm{NN}$ data set for $T_{\mathrm{lab}}<350\mathrm{}$ MeV is also reported and compared with those given by the phase shift analysis of Arndt et al. and by the phenomenological Reid soft-core potential.
