$\eta$ photoproduction off the deuteron and low-energy $\eta$-nucleon interaction

S. X. Nakamura, H. Kamano, T. Ishikawa

We study $\eta$ photoproduction off the deuteron ($\gamma d\to \eta pn$) at a special kinematics: $\sim 0.94$ GeV of the photon beam energy and $\sim 0^{\circ }$ of the scattering angle of the prot…
