Abstract: (APS)

We give some applications of the optical theorem (and its extensions) to charge exchange reactions of pions between isobaric analog states of nuclear targets, based on isospin invariance. We then derive an inequality, valid in the strong absorption limit, to give a bound on reaction channels which may be contributing to the isotensor optical potential, at pion energies near the 3,3 resonance. We further show that coupling to pion absorption on T=1 pairs may provide a major component of this potential.
