The spin correlation parameter [ital A][sub 00[ital N][ital N]] for 497.5 MeV proton + proton elastic scattering was determined over the center-of-momentum scattering angle region 23.1[degree]--64.9 [degree]. The new [ital A][sub 00[ital N][ital N]] extend to more forward angles than existing [ital A][sub 00[ital N][ital N]] and have significantly smaller statistical errors ([plus minus]0.01--0.04). The [ital A][sub 00[ital N][ital N]] are qualitatively described by recent phase shift analyses, but a quantitative shape and normalization discrepancy remains in the forward angle region. These new data provide important constraints for nucleon-nucleon spin-dependent amplitudes at forward angles which are used in theoretical models of nucleon-nucleus scattering.
