An extensive experimental program was carried out at MAMI (Mainz) and ELSA (Bonn) to measure pion photo-production reactions on the nucleon in double polarization and to investigate the Gerasimov-Drell-Hearn Sum Rule. We obtained results for the proton in the energy range from about 200 MeV to 3000 MeV and for the neutron, using a deuteron target, from about 200 MeV to 1900 MeV. Preliminary results on the total absorption cross sections are presented and discussed. [Copyright &y& Elsevier]
