Résumé
Au Laboratoire National de Brookhaven (AGS), la mesure de la puissance d'analyse d'une diffusion élastique p-p de 28 GeV/c a été effectuée à p⊥² = 5,95 et 6,56 (GeV/c)² en utilisant une cible de protons polarisée et un faisceau de protons non-polarisé. Les résultats montrent que la puissance d'analyse, A, augmente rapidement avec p⊥².

Abstract
The analyzing power in 28 GeV/c proton-proton elastic scattering was measured at p⊥² = 5.95 and 6.56 (GeV/c)² using a polarized proton target and an unpolarized proton beam at the Brookhaven National Laboratory AGS. Results indicate that the analyzing power, A, is rising sharply with p⊥².
