Summary:

Single polarization observables Σ, P, and T are investigated for the nucleon (p, n) and the trinucleon (³He, ³H). The threshold E{sub 0+} and the resonance M{sub 1+} and E{sub 1+} multipoles are particularly studied. For the reaction ³He(γ, π⁺)³H a recently developed nonlocal coupled-channel approach is presented that employs three-body Faddeev amplitudes and incorporates two-step processes such as ³He(γ, π{sup o})³He(π{sup o}, π⁺)³H. Enhancement effects of the contributions from small components of the ³He wave function as well as from the Δ resonance E2 transition to the polarization observables have been found.
