Abstract : Giant quantum oscillations in the attenuation of Rayleigh waves are studied on an unstressed metal surface and on a stressed one. In the first case the attenuation peak behaves according to the theory. Such an unbroadened peak is reported for the first time. If the metal surface is stressed, the attenuation peak suffers an inhomogeneous broadening which is explained by taking into account the deformation field near the surface.
