Abstract

The deuteron magnetic and quadrupole moments are unambiguosly determined within the front-form Hamiltonian dynamics, by using a new current operator which fulfills Poincaré, parity, and time reversal covariance, together with Hermiticity and the continuity equation. For both quantities the usual disagreement between theoretical and experimental results is largely removed.
