Descripción
Sumario:New experimental results are presented on proton-proton elastic scattering at centre-of-mass energies square root s=23 GeV and square root s=62 GeV. The data are obtained using the Split Field Magnet detector at the CERN Intersecting Storage Rings. The absolute differential cross-sections show an energy-dependent behaviour. The position of the diffraction minimum changes from t=(-1.44+or-0.02) GeV /sup 2/ at 23 GeV to (-1.26+or-0.03) GeV/sup 2/ at 62 GeV. The cross- section at the second maximum is increasing with square root s. The connection of these observations with the hypothesis of 'geometrical scaling' is discussed. (8 refs).
