Abstract
The time-dependence of absorption coefficient in metallic YBa2Cu3O6+x films is studied by the optical spectroscopy method. This process is i nduced by the electron-structure relaxation in the films after fast co oling to low temperatures. It is shown that in the superconducting pha se long-time relaxation is frozen while a short-time component of the relaxation, connected with the near-Fermi states of electrons, remains unchanged.
