pp elastic scattering polarization transfer K_(onno) and depolarization D_(onon) between 1.94 and 2.80 GeV

摘要

A polarized proton beam extracted from SATURNE II and the Saclay polarized proton target were used to measure the rescattering observables K_(onno) and D_(onon) at 26 energies from 1.94 to 2.80 GeV and at 0.80 GeV. The beam and target polarizations were oriented vertically and left-right as well as up-down asymmetries in the second scattering on carbon were measured. The present data, obtained in small energy steps, are practically constant as a function of energy at 90°CM, where K_(onno) = D_(onon). These data will bring about important modification to phase shifts and stabilize the solutions.
