[en] Proton-antiproton elastic scattering was measured at the centre-of-mass energy √s=546 GeV in the four-momentum transfer range 0.45 ≤-t≤ 1.55 GeV/sup 2/. The shape of the t-distribution is quite different from that observed in proton-proton scattering at the ISR. Rather than a dip-bump structure, a kink is present at -t≅0.9 GeV/sup 2/ followed by a shoulder. The cross section at the second maximum is more than one order of magnitude higher than at the ISR
