Аннотация

Point-contact spectroscopy has been used to study the electron–phonon interaction in osmium. Measurements were made of the second derivative of the current-voltage characteristics for point contacts in osmium, and the energy dependence of the point-contact electron–phonon interaction function has been determined (this function is the transport version of the isotropic Éliashberg electron–phonon interaction function). The free electron approximation was used to evaluate the absolute values of the point-contact electron–phonon interaction function and the electron–phonon interaction integral parameter for osmium. We discuss the possible shape of the Éliashberg electron–phonon interaction function and the density of phonon states.
