โœฆ Synopsis

We have studied nuclear quadrupole deformation effects in deeply bound pionic atoms theoretically. We have evaluated the level shifts and widths of the hyperfine components using the first order perturbation theory and compared them with the effects of neutron skin. We conclude that the nuclear quadrupole deformation effects for deeply bound ls and 2p states are very difficult to observe and that the effects could be observed for 3d states. We also conclude that the deformation effects are sensitive to the parameters of the pion-nucleus optical potential. (~) 1997 Elsevier Science B.V.

We study the structure and formation of deeply bound pionic atoms on ฮฒ-unstable nuclei. We calculate the eigenenergies of the pionic atoms using the model nuclear densities and the realistic pion-nucleus optical potential. We also investigate the formation cross sections of the deeply bound pionic a
