Abstract

Using one of the two possible representations of Coulomb scattering amplitude, a Generalized Sum-of-Differences (GSOD) formula is derived and discussed. It is shown that this new, Generalized SOD formula is not a special case of the Generalized Optical Theorem but is more general. The Modified SOD formula can be a useful toolfor very precise determination of absolute values of the elastic differential cross-section in certain situations. Such precision cannot be obtained using any other method.
