Abstract
We discuss the possibility of producing the bound states of the meson in nuclei theoretically. We calculate the formation cross sections of the bound states with the Green function method for the reaction and discuss the experimental feasibility at photon facilities such as SPring-8. We conclude that we can expect to observe resonance peaks in spectra for the formation of bound states and we can deduce new information on properties at finite density. These observations are believed to be essential to know the possible mass shift of and deduce new information on the effective restoration of the chiral anomaly in the nuclear medium.
