Abstract
The spin correlation parameter A00NN for 497.5 MeV proton+proton elast ic scattering was determined over the center-of-momentum scattering an gle region 23.1-degrees - 64.9-degrees. The new A00NN extend to more f orward angles than existing A00NN and have significantly smaller stati stical errors (+/-0.01 - 0.04). The A00NN are qualitatively described by recent phase shift analyses, but a quantitative shape and normaliza tion discrepancy remains in the forward angle region. These new data p rovide important constraints for nucleon-nucleon spin-dependent amplit udes at forward angles which are used in theoretical models of nucleon -nucleus scattering.
