The data on pp elastic scattering at 1.8 and 1.96 TeV are analyzed in terms of real and imaginary amplitudes, in a treatment with high accuracy, covering the whole t range, and satisfying the expectation of dispersion relation for amplitudes and for slopes. A method is introduced for the determination of the total cross section and the other forward scattering parameters and to check compatibility of E-710, CDF, and the recent D0 data. Slopes BR and BI of the real and imaginary amplitudes, treated as independent quantities, influence the amplitudes in the whole t range and are important for the determination of the total cross section. The amplitudes are fully constructed, and a prediction is made of a marked dip in d\ensuremathσ/dt in the |t| range 3--5 GeV2 due to the universal contribution of the process of three-gluon exchange.
