Baryon spectroscopy is important to understand Quantum Chromo-Dynamics (QCD) at low energies. We investigate exotic hadrons like pentaquark baryons which consist of five quarks at the lowest order of quark configuration. A nucleon resonance N (1670) which is observed in photoproduction on the neutron is a candidate of pentaquark baryons. A series of 2t0 and 77 photoproduction experiments was carried out with an electro-magnetic calorimeter FOREST at Research Center for Electron Photon Science (ELPH). Tohoku University. The incident tagged bremsstrahlung photon energy ranges from 550 to 1150 MeV. The differential and total cross sections were obtained for φ and η photoproduction processes on the proton and the deuteron. The analysis of the nucleon and delta resonance contribution in φ and photoproduction on the neutron is underway.
