Abstract

We performed a precision missing-mass spectroscopy experiment of the deeply bound pionic states in a 121Sn atom using the (d,3He) reaction near the π- emission threshold. The experiment serves as a pilot experiment for our new 'pionic atom factory project' at RIBF, which aims at precision spectroscopy of the energy spectrum of the pionic atom of isotopes and isotones. The result of the pilot experiment demonstrated the potentiality of BigRIPS and of the RIBF facilities for the project. The current status of the analysis is reported.
