Abstract
Using modern data, we first refit constants needed to complete an anomalous pi rho omegaa(1) Lagrangian obtained within the approach of hidden local s ymmetries, Then we derive from this Lagrangian electromagnetic isoscalar pi rho gamma and rhoa(1)gamma exchange currents needed in calculations of the deuteron electromagnetic form factors at large momentum transfers.
