N2 - Several cases of anomalously small level shifts and widths are known in pionic atoms. These lead to pion-nucleus potentials which are different from those describing all other "normal" pionic atoms. Data on the elastic scattering of 19.5 MeV π± by 12C and 40Ca and 30 MeV π± by 58,60,64Ni is in very good agreement with predictions made with normal potentials and clearly rule-out potentials obtained from the "anomalous" cases.
