Ravenhall, D.G. Mather, Lauren Richard 2011-07-12T18:29:23Z 2011-07-12T18:29:23Z 10000-01-01 1969 Relativistic effects in the electromagnetic form factors of a two-body bound system are discussed by examining specific examples in detail. The wave function for the two-body bound system is calculated from the Bethe-Salpeter equation and inserted into form factor expressions for scalar and vector photons. Even in the Breit frame, the charge density is distorted due to relativistic effects. The resulting form factor is compared to a static form factor which is calculated by not allowing the relativistic distortion in the charge density to occur. At low momentum transfers, relativistic distortion causes the initial slope of the form factor, plotted as a function of q2, to be greater in magnitude than the static case. This gives the system an apparent mean square radius that is larger than the actual mean square radius. At large momentum transfers the relativistic and static form factors appear to have the same functional form but differ in magnitude by a constant factor. The scalar photon form factor was three times greater and the vector photon form factor five times greater than the static form factors for the particular model that was considered.
