Title: Polarization phenomena in the reaction NN{yields}NN{pi} near threshold

Abstract

First calculations for spin-dependent observables of the reactions pp{yields}pp{pi}{sup 0}, pp{yields}pn{pi}{sup +}, and pp{yields}d{pi}{sup +} near threshold are presented, employing the Juelich model for pion production. The influence of resonant [via the excitation of the {delta}(1232)] and nonresonant p-wave pion production mechanisms on these observables is examined. For the reactions pp{yields}pn{pi}{sup +} and pp{yields}d{pi}{sup +} nice agreement of our predictions with the presently available data on spin correlation coefficents is observed whereas for pp{yields}pp{pi}{sup 0} the description of the data is less satisfying.
