Abstract: (APS)
The isospin decomposed Drell-Hearn-Gerasimov sum rule is examined. The single-pion photoproduction contribution is integrated out to 1.7 GeV in the laboratory photon energy. We obtain an improved estimate of the contribution of this process to the isovector and isovector-isoscalar sum rules. The qualitative features of Karliner's results remain valid. The isoscalar sum rule shows no indication of convergence.- photon p: exclusive reaction
