Electromagnetic Form Factors of Two-Nucleon and Three-Nucleon Bound States
The known e.m. deuteron and trinucleon form factors are theoretically described. The description is noncovariant with nucleonic degrees of freedom; single Δ-isobar excitation is allowed in the trinucleon bound states. The importance of two-nucleon exchange contributions to the charge and current operators for a successful account of the data as well as the ambiguities in their theoretical derivation are discussed; the two-nucleon charge operator is of relativistic order. Problems remain in simultaneously describing the existing deuteron and trinucleon data.
