Abstract
Bounds are obtained on near-forward scattering amplitudes that violate the Pomeranchuk theorem. It is proved that these amplitudes have zeros in . Experimental consequences are estimated, including phases of near-forward amplitudes, growth of the forward peak and shrinkage of its width, and possible oscillations. A narrow peak in the Coulomb region cannot be excluded and may invalidate experimental estimates of total cross sections.
