Abstract：
The η meson photoproduction off deutron γ d→ηX are calculated, where assuming the η photoproduction from nucleon is dominated by the N11*(1535), and the η-nucleon-nucleon vertex matrix element Γ_dpn is approximated using the non-relativistic deuteron wave function. The cross section and differential cross section can fit the new data well, and the coupling constant of γnN^* is obtained.
