Abstract

Results of the doppleron damping measurements of the temperature dependence of the scattering rate v ( T) for carriers on the non-central sections of the different sheets of the Fermi surface (FS) of molybdenum are presented. The α T 2 law has been found over the temperature range 1.5–5 K, with α practically the same for the electron jack and hole octahedron. The values of α are in a good agreement with those obtained from the radio-frequency size effect data for the central sections of the FS. From the analysis of these data and results obtained by other experimental methods it was concluded that the quadratic terms in the temperature dependence of the scattering rate in molybdenum is due to the electron-electron scattering. A discussion of the observation of electron-electron scattering in the non-transition metals is given.
