For {pi}{sup 0{eta}} photoproduction on the nucleon formal expressions are developed for the fivefold differential cross section and the recoil polarization including beam and target polarizations. The polarization observables are described by various beam, target, and beam-target asymmetries for polarized photons and/or polarized nucleons. They are given as bilinear Hermitian forms in the reaction matrix elements divided by the unpolarized cross section. Numerical results for the linear and circular beam asymmetries for {gamma}p{yields}{pi}{sup 0{eta}}p are obtained within an isobar model and are compared with existing data. Predictions are also given for the target asymmetry T{sub 11}, and the beam-target asymmetries T{sub 10}{sup c} and T{sub 11}{sup c} for circularly polarized photons.
