A measurement of p̄p and pp elastic scattering at ISR energies

Abstract

We have measured the differential cross section for pp and p̄p elastic scattering at √ s = 31, 53 and 62 GeV in the interval 0.05 < | t| < 0.85 GeV 2 at the CERN ISR using the Split Field Magnet detector. At 53 and 62 GeV, for 0.17 < | t| < 0.85 GeV 2 both pp and p̄p data show simple exponential behaviour in t; at √ s = 31 GeV the data for 0.05 < | t| < 0.85 GeV 2 are consistent with a change in slope near | t| = 0.15 GeV 2.
