Abstract
The interference at small of the Coulomb scattering amplitude and the nuclear amplitude is used to measure the phase of the nuclear scattering amplitude, and, hence, the value, where . The "normal" analysis of and elastic scattering uses a "spinless" Coulomb amplitude, i.e., a Rutherford amplitude () multiplied by a Coulomb form factor , an ansatz that pretends that the nucleon does not have any magnetic scattering. In this article, we investigate the role of the anomalous magnetic moment of the nucleon, . Given the method of analysis currently used by most published experiments, we conclude that the current experimentally inferred values of for should be systematically lowered by ≈0.005-0.0100 and, correspondingly, the values for should be systematically raised by the same amount. We discuss the theoretical uncertainties and a method of experimentally minimizing them.
