Abstract
The spin correlation parameters Aoonn, Aooss, Aoosk, Aookk and the analyzing power Aoono 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$^\circ$ to 164$^\circ$. 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.
