Polarization correlation in the scattering of polarized nucleons

Experiments concerning the spin correlation tensorC _pqik in the scattering of polarized nucleons on polarized nucleons are discussed. Relativistic formulae are derived for the experimental quantities. The scattering matrix is directly reconstructed with the help of experimentally measured quantities. The components ofC _pqik are predicted for np-scattering at 630 MeV and are given on graphs.On leave from Faculty of Technical and Nuclear Physics, Czech Technical University, Behová 7, Praha 1, Czechoslovakia.On leave from Nuclear Research Institute, Czechosl.
