A new phase-shift analysis of NN scattering in the energy range 15 -160 MeV is presented. The analysis is based on the carefully reviewed world pp +np data, including recent results for higher-order spin observables in n-p scattering. The latter are essential to determine the mixing parameter~& which is directly related to the isoscalar tensor force. c, displays a high trend, in agreement with recent analyses above 140 MeV, and is only reproduced by potential models with a strong tensor force. The prediction of the full Bonn potential is too low by 20% for energies above 40 MeV. All other I=O phase shifts show agreement with potential models; in particular, the notorious problem with 'P, around 50 MeV has disappeared. Around 25 MeV a ten parameter fit based purely on np data agrees with the corresponding At to the pp data and reveals no indication of anomalous charge independence breaking.PACS number(s): 21.30. +y, 13.75.Cs, 21.45. +v, 25. 10.+s

“…A full amplitude analysis of pp~t r+d has been attempted [3,4] and most major amplitudes are now fairly well determined. As for o,o(np), the cross section is reasonably well established at the present time; there are some asymmetry and spin-transfer data, as well, but by no means a complete set of measurements.…”

“…When a~decays into two photons of energy E, and E2, it can be shown that m 0 E1E2 = (3) 4 sin (g/2) where g is the opening angle between the two y rays. This is very important as it means that E,E2 is independent of the m energy.…”

We have studied the reaction p +p -+p+p+m from 320 to 500 MeV by detecting the y rays from m decay in coincidence in two large NaI crystals. The obtained differential and total cross sections of the pions are in agreement with previous measurements but are of a higher precision. We have also measured the pion analyzing powers; the first measurement of this observable. Our results are compared with those for the reactions np~N Nm. with confusing conclusions concerning the contribution of o. », the zero isospin pion production channel.

“…Therefore, one can easily rely on these data. These data are rather accurate for proton-proton (pp) system while minor uncertainties arise for dealing with neutron-proton (np) system [21].…”
