Measurement of the Nuclear Slope Parameter of thepp¯Elastic-Scattering Distribution ats=1800GeV

Abstract
We have studied proton-antiproton elastic scattering at s=1800 GeV at the Fermilab Collider, in the range 0.02<|t|<0.13 (GeV/c)2. Fitting the distribution by exp(B|t|), we obtain a value of B of 17.2±1.3 (GeV/c)2.
