Unity of relativistic corrections and meson exchange currents

Measurements of electron-deuteron scattering at high momentum transfer have stimulated considerable interest in the proper way to calculate meson exchange currents and relativistic corrections. In a recent short review given at the Zurich Conference, the relationship between various approaches to this problem and the interpretation of some correction terms was not clear. Today, all remaining ambiguities seem to be resolved, and in this short note I will briefly describe how exactly the same correction terms can be obtained from two very different approaches. I will limit myself to a comparison of the pion contribution to the deuteron charge form factor only. (orig./WL)
