Is there anomalous isospin breaking in the $\pi$N$rightarrow\pi$N S-wave?

The authors perform a phase-shift analysis of pi N to pi N within T /sub lab/=(300-600) MeV tolerating breakings of the order of 10% to find out if the present data allows for isospin breaking effects and to see in which partial waves they occur. (12 refs).
