We have systematically measured the electron dephasing scattering times from a three-dimensional weak-localization study of low-diffusivity thick (Formula presented) and (Formula presented) films. We find that the inelastic electron scattering rate (Formula presented) varies essentially linearly with the temperature and there is essentially no dependence of (Formula presented) on the electron elastic mean free path. This observation is understood in terms of the current theoretical concept for electron-electron scattering in strongly disordered bulk conductors.
