Meson properties are believed to have close connection to the fundamental theory, QCD, and have been studied for a long time both theoretically and experimentally. In this report, we study the recent activities in this field and consider the η(958) mesic nuclei and the deeply bound pionic atoms. We summarize the possible formation of the η(958) mesic nuclei by the (p, d) reactions and report the new possibilities of the spectroscopic study of the pionic atoms using the (d,3He) reactions.
