| We carried out the first missing mass spectroscopy of the 12C(γ,p) reaction with simultaneous detection of an η' meson. The experiment was performed using the BGOegg detector system at the LEPS2 beam line in SPring-8 with a 1.3-2.4 GeV photon beam. We evaluated cross-sections in different photon beam energy and different missing mass regions. The obtained cross-sections can be used to evaluate η'-nucleus optical potential from a comparison with theoretical calculations. |
