Description
The multipole expansion for electron–nucleus scattering within the electromagnetic theory has proven highly effective as it provides detailed information about the structure of nuclei. However, at the high energies achieved by electron accelerators (about 105 GeV at CERN since 2000), both the weak and electromagnetic interactions should be considered simultaneously. This presentation introduces a multipole expansion for electron–nucleus scattering at high energies, developed within the framework of the unified electroweak theory. Nuclear multipole form factors (including electromagnetic, vector, and axial components) are calculated directly using the many-particle shell model and fractional parentage coefficients, avoiding the approximations adopted in earlier studies. This approach opens new prospects for exploring the electroweak interaction in complex systems and advancing the understanding of nuclear structure.
