Spin correlation for pp elastic scattering at theta/sub c. m. / =. pi. /2 in the energy region of dibaryon resonances

Journal Article · · Phys. Rev. Lett.; (United States)
Precise measurements are reported of the spin-correlation parameter A/sub N/N for 500--800 MeV pp elastic scattering to theta/sub c.m/ = ..pi../2. While not reproducing the large value of A/sub N/N reported earlier at 697 MeV, the data show a pronounced maximum in the 90/sup 0/ triplet-to-singlet ratio near the location of the reported /sup 3/F/sub 3/ dibaryon resonance. In contradiction with an earlier report, structure is not found in the moduli of the singlet and triplet amplitudes.
