Proton-antiproton elastic scattering at a centre-of-mass energy of 540 GeV was measured in the four-momentum transfer range 0.05 < −t < s.19 GeV2. The t-distribution can be fitted by the exponential exp(b) with b=17.2±1.0 GeV−2. This result indicates a rapid decrease of the width of the diffraction peak between ISR and Collider energies.

Abstract
Proton-antiproton elastic scattering at a centre-of-mass energy of 540 GeV was measured in the four-momentum transfer range 0.05 < −t < s.19 GeV2. The t-distribution can be fitted by the exponential exp(b) with b=17.2±1.0 GeV−2. This result indicates a rapid decrease of the width of the diffraction peak between ISR and Collider energies.
