Résumé
Nous avons observé les structures petites mais très étroites dans la dépendance de moment des pouvoirs d'analyse dans la diffusion élastique proton-proton autour 1 GeV/c. Nous traîtons la possibilité d'une explication de ces structures en utilisant les résonances de deux-protons étroits.

Abstract
Small but rather narrow structures have been observed in the momentum dependence of the analyzing power in proton-proton elastic scattering around 1 GeV/c. A possible explanation for the structures using narrow two-proton resonances is discussed.
