Abstract
The effect of collisions on the giant quantum oscillations in the attenuation of both transverse and longitudinal acoustic waves propagating parallel to a dc magnetic field in metals is studied. This is accomplished by using the results of Tosima, Quinn, and Lampert on the theory of collision effects on the magnetoconductivity tensor of a quantum plasma. The experimental conditions under which quantum oscillations should be observable are determined, and the information which they yield about the Fermi surface is discussed.
