Abstract.
The spin correlation parameters \(A_{oonn}, A_{ooss}, A_{oosk}, A_{ookk}\) and the analyzing power \(A_{oono}\) have been measured in free np elastic scattering at kinetic energies of 260, 315, 380, 460 and 535 MeV in the c.m. angle range from 60° to 164°. The experiment was performed at the Paul-Scherrer-Institut (PSI) using a polarized neutron beam with continuous energy incident on a polarized proton target. These data will contribute significantly to the determination of the isospin I=0 nucleon-nucleon amplitudes.
