Abstract
We measured the differential cross section for proton-proton elastic scattering at 6 GeV/c, with both initial spins oriented normal to the scattering plane. The analyzing power $A$ shows significant structure with a large broad peak reaching about 24% near ${{P}_{\ensuremath{\perp}}}^{2}=1.6$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The spin-spin correlation parameter ${A}_{\mathrm{nn}}$ exhibits more dramatic structure, with a small but very sharp peak rising rapidly to about 13% at 90${\mathrm{\ifmmode^\circ\else\textdegree\fi{}}}_{\mathrm{c}.\mathrm{m}.}$. This sharp peak may be caused by particle-identity effects.
