Description

A new $\eta$ photoproduction experiment is planned for the determination of the $\eta$-$n$ low-energy scattering parameters at the Research Center for Electron Photon Science (ELPH), Tohoku University. The emitted proton is measured at 0 degrees for the $\gamma d\to petan$ reaction at $E_{\gamma }\sim 0.9$ GeV, which gives the zero relative momentum between the $\eta$ meson and the neutron. Two photons from the $\eta$-meson are measured using an electromagnetic calorimeter, FOREST. The detection of the $\eta$ meson is expected to select the condition $\eta n\to \eta n$. Prospects of the planned experiment to determine the $\eta n$ scattering length will be discussed.
