A method for the theoretical investigation of anisotropy of electron—phonon interaction is developed within the Hopfield‐McMillan approximation. Calculations for Ta, W, Ir, and Pt are carried out. The contributions of separate sheets of the Fermi surface to electron—phonon interactions are found, the origin of the anisotropy of both electron—phonon coupling constant and transport electron—phonon coupling constant is established for these metals.
