Abstract. A double scattering experiment, performed at the Paul-Scherrer-Institut (PSI), has measured a large variety of spin observables for free np elastic scattering from 260 to 535 MeV in the c.m. angle range from 60° to 164°. Results are presented for the depolarization parameters $D_{onon}, D_{os''os} and $D_{os''ok}$ , the polarization transfer parameters $K_{onno}, K_{os''so}$ and $K_{os''ko}$ , and the 3-index parameters $N_{onkk}, N_{os''kn}, N_{os''sn}$ and $N_{os'ʼns}$ . The last four parameters have been measured for the first time in this energy range. These measurements considerably improve the data base available for neutron-proton scattering and will allow a direct reconstruction of the I = 0 scattering matrix, providing complete information about the nucleon-nucleon interaction in a model-independent way.
