Abstract Semi-leptonic electroweak interactions in nuclei-such as β decay, μ capture, charged- and neutral-current neutrino reactions, and electron scattering-are described by a set of multipole operators carrying definite parity and angular momentum, obtained by projection from the underlying nuclear charge and three-current operators. If these nuclear operators are approximated by their one-body forms and expanded in the nucleon velocity through order | over(p, →) | / M, where over(p, →) and M are t...
