A relativistic plane wave formalism for quasifree eta meson photoproduction is presented. The sensitivity of the unpolarized differential cross section, the recoil nucleon polarization, and the photon asymmetry is investigated. The results indicate that the S11 resonance dominates the unpolarized differential cross section, but that its contribution to the spin observables are very small, for which the D13 resonance plays the primary role.
