POLARIZATION OBSERVABLES FOR THE COLLINEAR REACTION DP-]HE-3-PI(0)

Effects due to polarization of both colliding particles have been anal yzed in terms of two independent amplitudes that, in the general case, define the spin structure of the amplitude of the reaction dp --> He- 3 pi(0) in collinear geometry. The energy dependence of spin correlati on C-L,C-L,C-O,C-O due to longitudinal polarization of colliding parti cles is predicted using the moduli of amplitudes extracted from experi mental data. The limit of possible deviations is obtained for spin cor relation C-N,C-N,C-O,C-O due to transverse polarization of both partic les. The values of these polarization observables at threshold are pre dicted. The behavior of these polarization observables for the reactio n dp --> He-3 pi(0), having the same spin structure, is discussed.
