On the interference of the Coulomb and nuclear scattering amplitudes

A discussion is given of possible physical effects responsible for the behavior of the differential cross sections for p bar p scattering observed at the Sp bar pS collider in the region of the interference of the Coulomb and nuclear amplitudes, in particular, exchange of a maximal odderon and the role of the relative phase of these amplitudes. It is also noted that the procedure of fitting the experimental data admits comparatively small values of the real part of the amplitude, which can be described without any exotic assumptions
