- Abstract
Taking into account the different forms of the Coulomb-hadron interference phase and the possible spin-flip contribution the new analysis of the experimental data of the proton-antiproton elastic scattering at 3.8<pL<6.0 GeV/c and small momentum transfer is carried out. It is shown that the size of the spin-flip amplitude can be determined from the form of the differential cross-sections at small-t, and the deviation of ρ(s, t) obtained from the examined experimental data of the $p\bar{p}$ scattering from the analysis1, based on the dispersion relations, is conserved in all examined assumptions. The analysis of the proton-proton elastic scattering at 9<pL<70 GeV/c also shows the impact of the examined effects on the form of the differential cross-sections.
