Abstract

Strong-interaction shifts and widths in pionic atoms of Al, Si, S, Ca, Fe, Cu, Zn, Ag, Cd, Pb, Bi and U have been measured. Various forms for an effective pion-nucleus potential have been fitted to the data for 2p levels and the predictions of these potentials compared with the results for 3d and 4f levels. The predictions have also been compared with available data for 1s states. The effects on pionic atoms of strongly bound pionic states, which it has recently been suggested might exist, are discussed.
