The GDH Experiment on the Deuteron at MAMI — •Oliver Jahn — Institut für Kernphysik, Mainz

The GDH sum rule connects ground state properties of the nucleon with helicity dependent cross sections. To investigate these cross sections on the deuteron, experiments have been carried out in the A2-Collaboration at the Mainz Microtron, Germany, in 1998 and in 2003, using circularly polarised photons on a polarised d-butanol target. The latest analysis results and the status of the new GDH experiment with the Crystal Ball detector are reported.
