Spectral distribution functions of electron-phonon interaction alpha
2F( omega ) obtained by ab initio linear-response calculations are used
to describe various superconducting and transport properties in a number
of elemental metals such as Al, Cu, Mo, Nb, Pb, Pd, Ta, and V. Their lattice
dynamics and self-consistently screened electron-phonon coupling are evaluated
within local density functional theory and using a linear-muffin-tin-orbital
basis set. We compare our theoretical alpha 2F( omega ) with those deduced
from the tunneling measurements and find a close agreement between them.
Temperature-dependent electrical and thermal resistivities as well as transport
constants lambda tr also agree well with the experimental data. The values
of lambda tr are close to the electron-phonon coupling parameter lambda
. For the latter a very good agreement with specific-heat measurements
was found without any paramagnon contribution, except in Pd. We conclude
that our method provides the description of electron-phonon interactions
in tested materials with an accuracy of 10%.
