  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 < p_L
<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 $\rho(s,t)$
obtained from the examined experimental data of the $p\bar{p}$ scattering from
the analysis \cite{Kroll}, based on the dispersion relations, is conserved in
all xamined assumptions. The analysis of the proton-proton elastic scattering
at $9 < p_L < 70 \ $GeV/c also shows the impact of the examined effects on the
form of the differential cross sections.
