The nucleon-nucleon triple scattering parameters for recoil particles

Relativistic formulae are obtained, expressing the polarization of the initially unpolarized particle in the scattering of an unpolarized nucleon on a polarized one, in terms of the polarization transfer tensor and in terms of the scattering matrix elements.On leave of absence from theFaculty of Technical and Nuclear Physics, Czech Technical University, Prague, Czechoslovakia.On leave of absence from theNuclear Research Institute of the Czechoslovak Academy of Sciences, e, Czechoslovakia.In conclusion the authors express their profound gratitude to S. M. Bilenky, L. I. Lapidus, R. M. Ryndin and Ya. A. Smorodinsky for useful discussions and to E. Dudova and J. Fingerova for help in the work.
