Abstract
The role of anharmonicity of the phonon spectrum in superconductivity is discussed. The anharmonic phonon-electron coupling is calculated under quasiharmonic approximation. A procedure for calculating this coupling from the neutron data is outlined. The superconductivity in metal-hydride (deuteride) systems is discussed in the light of aforementioned anharmonic phonon-electron coupling.Keywords
