Description

The analysis of pionic atom data of 1s and 2p levels for N=Z spin-zero nuclei, in terms of an improved optical potential is presented. We find a strong (unexplained) s-wave repulsion and evidence for finite-range effects. The need for a relativistic treatment of the pion-nucleus interaction is discussed. (orig.)
