ResumoTotal reaction cross sections of 20 MeV π− and 30 MeV π+ and π− have been measured for carbon and nickel targets. The experimental results are in very good agreement with calculations based on commonly accepted pion-nucleus potentials but disagree with calculations based on the potentials associated with the so-called pionic atom anomaly.
