Scientific paper

The point-contact spectroscopy, in contrast to the tunneling spectrocopy, considers small electrical contacts with direct conductivity. In the normal state, it enables one to measure the spectral function of electron-boson interaction. In the superconducting state, new features appear connected with the energy dependence of excess current. The non-linearities of the current-voltage characteristic are due to: i) The inelastic scattering of electron quasiparticles in the contact region; ii) The energy dependence of the superconducting energy gap, and iii) The non-equilibrium superconducting effects. These effects are discussed from the experimental point of view
