From a knowledge of the π + p and π - p elastic differential cross-sections and polarizations below the inelastic threshold, we can predict the charge-exchange cross-section and polarization, and all the A and R parameters. However, in the inelastic region, a measurement of all observables is not sufficient to remove a continuum ambiguity in the determination of the phase-shifts.En dessous du seuil inélastique, on peut déduire de la seule connaissance des sections efficaces différentielles et polarisations des réactions élastiques π + p et π - p, la section efficace différentielle et la polarisation d'échange de charge, ainsi que tous les paramètres A et R. Par ailleurs, au-dessus du seuil inélastique, la mesure de toutes les observables n...
