Résumé
Nos mesures du pouvoir d'analyse vectoriel dans la diffusion élastique πd à 50 MeV sont en accord avec les prédictions des modèles qui incluent la partie P₁₁ du potentiel πN intégral mais sont en désaccord avec ceux qui omettent ou suppriment cette composante.

Abstract
Measurements of the vector analyzing power in πd elastic scattering at 50 MeV are found to agree well with model calculations that include the full πN P₁₁ potential and disagree when this is omitted or suppressed.
