Abstract
The method of electron tunneling is used to study the electron–phonon interaction in niobium and tantalum in the pressure interval 0–9 kbar. It is shown that the superconductivity of these metals is caused by the electron-phonon Cooper pairing mechanism. The method of determining the electron–phonon interaction function from tunnel spectroscopy data of these superconductors is improved.Keywords
