On the model-independent evaluation of inelastic electron scattering data at low momentum transfer

Abstract

At low momentum transfer, electro-excitation experiments may be corrected for the static Coulomb effects in a model-independent way. This is demonstrated in the case of magnetic transitions for various phenomenological current and magnetization distributions. The inclusion of a finite excitation energy gives mainly a kinematical effect. It is further shown that for transverse transitions the notion of a “transition radius” has no model-independent physical meaning and should be avoided.
