The Role of Spin Observables in Quasi-Free η Meson Photoproduction from Nuclei

Quasi-free eta meson photoproduction is studied within a relativistic plane wave impulse approximation. The sensitivity of the unpolarized differential cross-section, the recoil nucleon polarization, and the photon asymmetry are investigated. The results indicate that the spin observables are sensitive to subtle effects that are not accessible by only looking at the unpolarized differential cross-section.
