Abstract
Energy spectra of positive and negative pions from the processes n + p --> pi+/- + N + N have been measured for incident neutron energies fr om 460 to 560 MeV at average emission angles of 90-degrees and 166-deg rees in the centre of mass system. A significant asymmetry in the prod uction of pi+ and pi- has been found at backward angles. This result m anifests a significant contribution of the non-resonant pion productio n from an isoscalar initial state.
