Mesonic processes in deep-inelastic electron scattering from nuclei
TL;DR: Inelastic electron scattering is considered in the energy and momentum transfer region associated with the quasielastic and 3-3 resonance pion electroproduction peaks in this paper, and the MEC contribution is found to be significant in this region, and helps to account for the discrepancy between theory and experiment.

Electron scattering by nuclei
TL;DR: In this article, a detailed survey of the available experimental data concerning the electron-nucleus interaction is presented, and the theoretical interpretation of the experimental data in terms of microscopic wave functions is thoroughly discussed and the effects of meson exchange currents are also considered.

Electromagnetic meson-exchange currents at the nucleon mass scale
TL;DR: In this paper, the meson-exchange current operators are derived in the soft-pion limit and further extended at high momentum transfer via an effective model Lagrangian, and contributions of meson exchange currents in heavy nuclei are discussed, and connections with the present relativistic description of nuclear systems are given.
