摘要：

Spin observables for electro- and photoproduction of neutral pions on the deuteron are derived. The number of independent amplitudes and observables is discussed and the expression of the observables in terms of ratios of cross-section combinations is given. Besides these model-independent results, approximate symmetries in the observables are discussed. These symmetries become apparent when some simplifying assumptions are made. The latter are relevant, as the full model gives results that are in many cases close to the results for the simplified model.
