Formation of Deeply Bound Pionic Atoms and Pion Properties in Nuclei

Abstract

We report the recent theoretical studies for the formation of deeply bound pionic atoms. It is important to know the pion properties in nuclei since they are believed to provide valuable information on the aspects of the symmetry of strong interaction at finite density. In order to deduce precise information on the pion properties in nuclei from observables of the deeply bound pionic atom, we consider the pionic atom formation on the even-even and neutron-odd nucleus targets. Furthermore, we also calculate the formation spectra using the Green's function method. Theoretical results using the Green's function method will be necessary to investigate the high precision data which will be obtained in near future.
