14th International Workshop on Meson Production, Properties and Interaction, Cracow, Poland, 2 Jun 2016 - 7 Jun 2016; The European physical journal / Web of Conferences Web of Conferences : proceedings proceedings 130, 02010 (2016). doi:10.1051/epjconf/201613002010 We performed a missing-mass spectroscopy experiment of the ^12C(p, d) reaction at 2.5 GeV proton energy in order to search for eta' mesic nuclei. An excitation-energy spectrum of ^11C was obtained around the eta' production threshold. As no significant peak structure was observed in the spectrum, upper limits of the formation cross section of eta' mesic nuclei have been determined. Preliminary results of the experiment as well as future prospects are given. Published by EDP Sciences, Les Ulis
