摘要：

The photonuclear sum rule of Gerasimov is revisited and found to be violated for both a Dirac particle and spin current contributions. For a relativistic particle a modified sum rule is derived which is consistent with the Gell-Mann, Goldberger, and Thirring sum rule. In the case of nonrelativistic spin currents, violation of causality leads to a strong violation of dispersion sum rules.
