The spectroscopy of deeply bound pionic atoms provides a way to understand the restoration of chiral symmetry breaking at finite density. We have been performing a series of experiments of missing-mass spectroscopy of the (d,3He) reaction at RIBF to investigate pionic atoms of several Sn isotopes. [...]

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. [...]

We conduct an experimental project to make spectroscopy of deeply bound pionic atoms systematically over wide range of nuclei. We aim at studying the strong interaction in the low energy region, which has close connection to spontaneous chiral symmetry breaking and its partial restoration in nuclear matter. [...]

We present a model for the study of the excitation of Delta(1232) and N^*(1440) resonances in isobaric charge-exchange (^AZ, ^A(Z +- 1)) reactions of heavy nuclei. Quasi-elastic and inelastic elementary processes contributing to the double differential cross sections of the reactions are described in terms of the exchange of virtual pions. [...]

The EXL project aims to study nuclear structure by direct reactions in inverse kinematics at the storage rings of the future FAIR facility. In this contribution, we present the status of the project: the technical implementation at the ESR at GSI and preliminary results of the EXL campaign in 2012, the first using also a radioactive beam..
