Abstract

We measured the analyzing power A and the spin-spin correlation parameter Ann in medium-P 2 proton-proton elastic scattering, using a polarized-proton target and the 18.5-GeV/c Brookhaven Alternating-Gradient Synchrotron polarized-proton beam. We found sharp dips in both A and Ann, which occur at different P 2 values. The unexpected sharp structure in the spin-spin force occurs near P 2=2.3 (GeV/c)2 where the elastic cross section has no apparent structure.
