Abstract
The term in the scattering amplitude is commonly evaluated at squared nucleon momentum transfer , where is the pion mass. Because of the nonanalytic nature of perturbations about the chiral SU(2) × SU(2) limit, differs from by a term linear in . We calculate the difference term exactly to and find
