Query: Relativistic and Polarization Phenomena in NN -> D\pi processes   A detailed analysis of the processes of the type NN -> D\pi is presented
taking into account the exchange graphs of a nucleon and a pion. A large
sensitivity of polarization observables to the off-mass shell effects of
nucleons inside the deuteron is shown. The influence of the inclusion of the
P-wave in the Deuteron Wave Function (DWF) is studied. We have analysed the
sensitivity of all the observables to the form of \pi NN - current taking into
account the off-shellnis of the nucleon and the choice of the DWF relativistic
form. One can see the very large sensitivity of all the observables, especialy
of the polarization characteristics to the choice of the DWF form. The
inclusion of the P-wave contribution to the DWF within framework of Gross's
approach results in a better description of the experimental data on the
differential cross section and the polarization observables.
