PHASE-SHIFT ANALYSIS OF ALL PROTON-PROTON SCATTERING DATA BELOW TLAB=350 MEV

As a continuation of our 030 MeV analysis we present a multienergy phase shift analysis of all pp scattering data below Tlab=350 MeV. In the description of all partial waves we take exactly into account the long-range potential consisting of the improved Coulomb potential (including the magnetic moment interaction), the vacuum polarization potential, and the tail of the one-pion-exchange potential. To describe the short-range interaction in the lower partial waves we use a P-matrix parametrization. The intermediate partial waves are treated either by optimal mapping techniques or by using the Nijmegen soft-core potential. The latter gives a better description of the data. The final data set comprises 1626 scattering observables. The best fit to this final data set results in 2/Ndf=1.117, where Ndf=1576 is the number of degrees of freedom. The pp0 pseudovector coupling constant is determined to be f02=(74.90.7)×10-3. Single-energy phase shifts and errors are also given. © 1990 The American Physical Society.
