Analyzing Powers and Spin Correlation Coefficients for p+d Elastic Scattering at 135 and 200 MeV

摘要

The proton and deuteron analyzing powers and 10 of the possible 12 spincorrelation coefficients have been measured for p+d elastic scattering atproton bombarding energies of 135 and 200 MeV. The results are compared withFaddeev calculations using two different NN potentials. The qualitativefeatures of the extensive data set on the spin dependence in p+d elasticscattering over a wide range of angles presented here are remarkably wellexplained by two-nucleon force predictions without inclusion of a three-nucleonforce. The remaining discrepancies are, in general, not alleviated whentheoretical three-nucleon forces are included in the calculations.
