N2 - Among the two-body dynamics of the meson-nucleon systems, the attractive interaction between the eta meson and nucleon is not well-known. A new photoproduction experiment is planned for the determination of the low-energy scattering parameters between the eta meson and nucleon at the Research Center for Electron Photon Science, Tohoku University. The emitted proton is measured at 0° for eta photoproduction on the deuteron at the incident energy of 0.94 GeV, which gives small relative momentum between the eta meson and neutron in the final state to increase rescattering probability. The kinematics is found to have a good resolving power of the scattering length and effective range. In this contribution, the current status of the new experiment is presented.
