Variation des déphasages de la diffusion p-d près du seuil de cassure du deuton

Measurements of the p-d elastic scattering differential cross-section between 3.14 and 3.74 MeV, around threshold for the deuteron break-up, have been carried out and a phase-shift analysis shows an interesting variation of the 2S1/2 partial wave, unnoticed in the older measurements at 1 MeV steps.
