Electron inelastic lifetime and electron-electron attraction strength in Al films

Abstract
Magnetoresistance measurements on 100-Å films of granular Al from 3 to 20 K are reported and evaluated using the localization and interaction theories. The electron inelastic scattering rate is well fitted by a sum of terms due to electron-electron and electron-phonon scattering. The electron-electron attraction strength, β(T), is in good agreement with Larkin's theory.
