Abstract:
The Axx and Ayy spin correlation coefficients of proton-proton scattering have been measured at Elab = 46.9 MeV and θc.m. = 90° with the same experimental techniques already used at Saclay from 11 to 26 MeV and at Grenoble at 37.2 MeV. For Axx the deviation from the predictions of the energy-dependent phase-shifts analysis of Livermore is significant (≈ 3.7 standard deviations) but not as large as for the 47.5 MeV Tokyo measurement. For Ayy the agreement is very good.
