The article presents the multipole expansion for the electron-nucleus scattering cross-section at high energies within framework of the unified electroweak theory. The electroweak currents of  the nucleus is expanded into simple components with definite angular momentum, which are called the multipole form factors. The multipole expansion of the cross-section is a consequence of the above expansion. Besides the familiar electromagnetic form factors FxL , there are new form factors VLX and ALX related to weak interactions, corresponding to the vector and axial weak currents. The obtained general expressions are applied to the nucleus 36Li , where the partial form factors are computed in the multiparticle shell model.

What I have to say will consist largely of speculation, because no unusual feature of muon interactions at high energies has yet been established. Considerable efforts have been made in the last few years to find an anomalous effect, but so far the result has been negative. This is probably because we have not yet reached high enough energies, as will become evident during the course of this talk. Figure 19 shows a number of possible interactions of the muon, which will be considered in detail below. There is first the electromagnetic coupling to the photon, with coupling constant e satisfying e 2 = 1/137 (figure 19( a )). Figure 19( b ) shows the weak interaction coupling, to the intermediate boson W ± (which is here assumed to exist). To obtain the correct strength for the overall weak four-fermion interaction one requires g 2 / m 2 w = G weak = 10 -5 / m 2 N , where m N is the nucleon mass. Thus only the ratio of g 2 to m 2 w is fixed.
