✦ Synopsis

Using modern data, we first refit constants needed to complete an anomalous πρωa 1 Lagrangian obtained within the approach of hidden local symmetries. Then we derive from this Lagrangian electromagnetic isoscalar ρπγ and ρa 1 γ exchange currents needed in calculations of the deuteron electromagnetic form factors at large momentum transfers.
