We plan a missing-mass spectroscopy experiment of η′ mesic nuclei with the 12C(p,d)η′⊗11C reaction to study in-medium properties of the η′ meson. In nuclear medium, due to restoration of chiral symmetry, the mass of the η′ meson may be reduced, and η′ bound states in a nucleus may exist. The experiment will be started at GSI with a 2.5 GeV proton beam using FRS as a spectrometer and will be continued at Super-FRS at FAIR. The plan of the experiment and development of a Cherenkov detector and an optics mode are described.
