We performed a missing-mass spectroscopy experiment of the 12C(p, d) reaction at 2.5 GeV proton energy in order to search for η′ mesic nuclei. An excitation-energy spectrum 11C was obtained around production threshold. As no significant peak structure observed spectrum, upper limits formation cross section nuclei have been determined. Preliminary results as well future prospects are given.
