Abstract
A relativistic meson-nucleon two-body equation applicable to the elastic nonexchange scattering of negative pions by protons is solved using the lowest order interaction kernel. The scattering matrix which this equation yields is shown to be unitary. The total cross section calculated from this scattering matrix is finite at threshold and relatively independent of the coupling constant. A plot of the cross section as a function of energy is included.
