The η′ meson mass may be reduced due to partial restoration of chiral symmetry. If this is the case, an η′-nucleus system may form a nuclear bound state.We plan to carry out a missing-mass spectroscopy experiment with the 12C(p,d) reaction at GSI-SIS. Peak structures corresponding to such a bound state may be observed even in an inclusive measurement, if the decay width is narrow enough.
