Status of the GDH Experiment on the Deuteron at MAMI — •Oliver Jahn — Institut für Kernphysik, Becherweg 45, 55099 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 polarized photons on a polarized d-butanol target. A status report of the data analysis and latest results from the pilot experiment of 1998 are given.
