Abstract: A general formalism for double and triple spin correlations of the reaction (N) over right arrow(N) over right arrow -> (Delta) over right arrowN is developed for the case of collinear kinematics. A complete polarization experiment allowing one to reconstruct all four amplitudes describing this process is suggested. Furthermore, the spin observables of the inelastic charge-exchange reaction (p) over right arrow(d) over right arrow. -> (Delta) over right arrow (0)(pp)(S-1(0)) are analyzed in collinear kinematics within the single pN-scattering mechanism involving the subprocess pn -> Delta(0)p. The full set of spin observables, related to the polarization of one or two initial particles and one final particle, is obtained in terms of three invariant amplitudes of the reaction pd -> Delta(pp)(S-1(0)) and the transition form factor d. (pp)(S-1(0)). A complete polarization experiment for the reaction (p) over right arrow(d) over right arrow. -> (Delta) over right arrow (0)(pp)(S-1(0)) is suggested which allows one to determine three independent combinations of the four amplitudes of the elementary subprocess (N) over right arrow(N) over right arrow -> (Delta) over right arrowN.
