AB  - Preliminary results for the double polarisation observable E and the corresponding helicity dependent cross sections σ<sub>1/2</sub> and σ<sub>3/2</sub> of η photoproduction off quasi-free protons and neutrons have been obtained by a recent experiment at the MAMI electron accelerator at Mainz, Germany. The results will help to constrain the origin and quantum numbers of the bump-like structure in the η cross section off the neutron.
