An energy dependent phase shift analysis of proton-proton scattering between 700 and 1300 MeV

F. Lehar , C. Lechanoine-Leluc , J. Bystricky

An energy dependent pp ⇒ pp phase-shift analysis for elastic proton-proton scattering is reported in the energy range between 700 to 1 300 MeV. Almost all phase shifts smoothly connect with the previous results of the Saclay-Geneva phase shift analysis below 800 MeV. Due to recent Satume II results the data base is now sufficiently abundant to perform such an analysis. Present results strongly disagree with the predictions of Arndt et al., for most phase shifts. Argand diagrams suggest a non-resonant behaviour of the 3F 3 partial wave and a resonance-like behaviour for the 1G 4 partial wave.
