Fifth-order differential cross sections,
(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI)
have been measured for the reaction n+p(--->)p+p+(pi)('-) at an incident neutron energy of 790 (+OR-) 5 MeV. The experiment was performed at the Clinton P. Anderson Meson Physics Facility (LAMPF). Kinematically complete data were obtained at eleven angular settings spanning the available phase space. Both kinematic loci were detected at five of the settings while only the large phase space locus was detected for the other six angles.
The protons were detected by MWPC counters on two spectro-meter arms which measured the vector momenta, P(' )=(' )(P,(theta),(phi)) for the scattered protons.
The measured cross sections have been combined with earlier measurements of the p+p(--->)p+p+(pi)(DEGREES) reaction at 800 MeV to extract estimates of the magnitudes of the non-resonant scattering amplitudes, (VBAR)A(,01)(VBAR) and (VBAR)A(,11)(VBAR), as a fraction of the resonant amplitude (VBAR)A(,13)(VBAR). More accurate calculations of the amplitudes await a theory that can describe the differential cross sections for these reactions.
