[en] The second derivative of the current-voltage characteristic of the point contacts and the double differential cross section for scattering of neutrons in ruthenium are measured. The phonon density of states function F(ω) and electron-phonon coupling function g_pc(ω) are determined on the basis of the experimental data for various symmetry directions in the single crystal and for a polycrystalline sample. An anisotropy of g_pc(ω) is observed in the single crystal. The g_pc(ω) functions are consistent with respect to the position of the singularities but differ with respect to relative intensity. The g_pc(ω) and F(ω) functions are compared with the data for other transition hexagonal closely packed metals
