    "abstract": "We present predictions for the spin structure functions of the proton and the\nneutron in the framework of a unitary isobar model for one-pion photo- and\nelectroproduction. Our results are compared with recent experimental data from\nSLAC. The first moments of the calculated structure functions fulfill the\nGerasimov-Drell-Hearn and Burkhardt-Cottingham sum rules within an error of\ntypically 5-10% for the proton. For the neutron target we find much bigger\ndeviations, in particular the sum rule for I_1(0)+I_2(0) is heavily violated.",
