The deuteron form factors are calculated using two model wave functions obtained from the 2007 CST high precision fits to np scattering data. Included in the calculation are a new class of isoscalar np interaction currents which are automatically generated by the nuclear force model used in these fits. If the nuclear model WJC2 is used, a precision fit (χ 2 /datum 1) to the Sick Global Analysis (GA) of all ed elastic scattering data can be obtained by adjusting the unknown off-shell nucleon form factors F3(Q 2 ) (discussed before) and F4(Q 2 ) (introduced in this paper), and predicting the high Q 2 behavior of the neutron charge form factor GEn(Q 2 ) well beyond the region where it has been measured directly. Relativistic corrections, isoscalar interaction currents, and off-shell effects are defined, discussed, and their size displayed. A rationale for extending ed elastic scattering measurements to higher Q 2 is presented. arXiv:1908.09421v1 [nucl-th]

We show an original way to build up a new family of electromagnetic meson exchange current operators via the method of unitary clothing transformations.Being introduced in such a way they do not depend on the choice of states with which we calculate the matrix elements. The new expressions for meson exchange currents have been compared with ones derived within the previous explorations. Special attention is paid to the deuteron eigenvalue problem and finding the proper deuteron states in a moving frame. An effective technique of ensuring the gauge independence based upon generalization of Siegert's theorem is proposed. Magnetic form factor of the deuteron is calculated with both one-body and twobody mechanisms. The influence of relativistic effects in the one-body calculation have been considered. Besides, separate contributions from the different meson exchange mechanisms are discussed.
