Assuming that the space integrals of source terms (sources) in the Klein-Gordon equation for the pion fields together with isospin generators form an SU(2)⊗SU(2) algebra which, in the soft-pion limit, is a good symmetry of the strong interactions, we calculate S-wave scattering lengths for the collision of pions with hadron targets as well as the pion-nucleon coupling constant. The results are in excellent agreement with experiment.
