Abstract: We have performed an inclusive spectroscopy of 122 Sn(d , 3 He) reaction near the pion emission threshold at an incident energy of Td = 250 MeV/nucleon. The first experiment aims as devloping the high precision spectroscopy of pionic atoms at the RI beam factory (RIBF) of RIKEN, which leads to a new project, pionic Atom Factory project (piAF) to measure pionic atoms for a wide range of elements. We report the analysis status of the pilot experiment.
