Influence of the electron-phonon interaction on the de Haas-van Alphen effect in mercury

Abstract
Accurate measurements of the de Haas-van Alphen effect amplitudes in mercury show departures from the theory of Lifshitz and Kosevich (1956). These departures are in accordance with the theory of Engelsberg and Simpson (1970), and are due to the breakdown of the quasiparticle picture of the electrons in the presence of electron-phonon interactions.
