Recent experiments on pi /sup plus or minus /p elastic scattering in the energy range 3 to 17 Bev/c show that the width of the diffraction peak is constant in contrast to the strongly decreasing width of the p-p peak. This result is in contradiction with the simple prediction from the Regge pole expansion, that high-energy elastic scattering is entirely controlled by the Pomeranchuk pole in the crossed channel and hence all diffraction peaks should shrink as the logarithm of the total center of mass energy squared. It is concluded that even taking the nucleon spin in the pi N scattering into account but making the assumption that the only singularities are moving poles in the complex j-plane, the theory cannot account for both a nonshrinking pi /sup -/ peak and a shrinking p-p peak.
