Abstract
An intensive program of n-p measurement of spin observables in elastic and pion production reactions has been performed at the Paul Scherrer Institute taking advantage of the high intensity polarized neutron beam. In the elas tic reaction 16 different spin observables have been measured for kinetic e nergies from 210 to 590 MeV with the centre of mass angular range from 60 t o 180 degrees. This will allow to perform direct reconstruction in the mode l independent way of the isospin 1=0 scattering amplitudes in elastic NN in teraction. Three body final state process (n) over right arrow p - pp pi(-) with polarized neutrons in exclusive experiment has been investigated.
