The analyzing powers ANand spin correlation parameters ANN, ASS, and ASLof the elastic proton-proton scattering have been measured with an internal polarized atomic beam target at the cooler synchrotron COSY. Excitation functions were taken continuously during the acceleration and deceleration of the internal beam for kinetic energies ranging between 0.45 and 2.5 GeV and scattering angles 30°≤Θc.m.≤90°. The analyzing power excitation functions provide a new polarization standard in the GeV region. The spin correlation data on ASSdisagree strikingly with existing phase shift solutions. The addition of the new polarization data to the world database removes some of the ambiguities in the phase shift solutions and the direct reconstruction of scattering amplitudes. The data are compared with a recent extension of a meson-exchange potential model to higher energies.

Correlation Parameters

In proton-proton scattering, when both incident and target protons have polarizations of P 1 and P 2 respectively in a direction normal to the plane of scattering, the differential cross-section, σ, at angle θ is given by σ( θ ) = σ 0 ( θ ) {1 + ( P 1 + P 2 ) P 3 ( θ ) + P 1 P 2 C NN ( θ )}. P 3 ( θ ) and C NN ( θ ) are the polarization and spin-correlation parameters of proton-proton scattering, and are functions of incident proton energy and scattering angle. The Harwell synchrocyclotron provides a choice of two proton beams at an energy of 142MeV ( a ) high intensity P 1 = 0, and ( b ) low intensity P 1 = ±0.48. P 3 ( θ ) is a well-known quantity, and the two remaining unknowns, P 2 and C NN ( θ ) can be obtained by comparing differential cross-sections measured with beams ( a ) and ( b ). Somewhat higher precision is obtainable in such a measurement of the target polarization P 2 than by either of the existing solid-state methods (Schmugge & Jeffries 1962; Abragam, Borghini & Chapellier 1962).
