We present a model of backward π+p, π−p, and π−p charge exchange scattering consistent with our earlier approach to forward π−p charge exchange and backward π+p. We consider two body differential cross section data which exhibits a dip–bump structure as well as nonzero polarization. This is explained in terms of a dominant Regge pole vanishing at the dip accompanied by a background. The background is primarily responsible for the large u behavior of the cross section which includes the rise after the dip. It is assumed that the presence of nonzero polarization dictates this behavior. We isolate the I = 3/2 amplitude in π−p backwards and determine the I = 1/2 amplitude from π+p backwards. A prediction for π−p → nπ0 follows.

By a phenomenological choice of the residue functions, a very good fit with experiment for the pion-nucleon charge exchange reaction at Fermilab energies is obtained on a simple Regge-pole model using a quadratic p trajectory and energy-independent parameters.
