Experimental results on the temperature dependence of the amplitude of time-of-flight effect signals in silver are presented. It is shown that it is possible to determine the electron-phonon scattering rate in the form of, on the one hand, an average over a certain orbit and, on the other hand, a point-by-point determination on the Fermi surface of the metal considered. The anisotropy of the electron-phonon scattering rate v(k) is obtained for the {100} plane from measurements of the amplitude of time-of-flight signals for two silver samples with the normals n∥〈100〉 and n∥〈110〉, respectively, for the magnetic field direction B∥〈100〉. From the analysis of the data, combined with results obtained earlier by means of the radiofrequency size effect, it is suggested that the electron-phonon scattering rate is frequency dependent; however, more experiments are needed to verify this conclusion.
