Isospin mixing as a source of enhanced isospin violation in pi N scattering
A small eta impurity in pi /sup 0/ can sometimes cause large deviations from isospin invariance in pi /sup -/p to pi /sup 0/n, and could account for the observed experimental indications of violation of the backward isospin bounds below 1 GeV/c. Possible large effects of mixing between formed N*...
