Spinobservables in Proton-Proton Elastic Scattering — •Heiko Rohdjeß — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn
The EDDA experiment at the COSY-accelerator in Jülich has measured analyzing powers and spin-correlation parameters at energies 0.5-2.5 GeV and c.m. scattering angles 300-900. Data was acquired with the EDDA detector and a polarized atomic-beam target internal to the unpolarized or polarized proton beam of COSY. Final data will be shown and the implication on our knowledge of elastic scattering, like phase-shifts, amplitudes and models of the nucleon-nucleon interaction, will be discussed. This work is supported by the BMBF and FZ-Jülich.
