Abstract

The effect of a planar Fermi surface on the phonon spectrum near q = 2p_F is investigated. Two branches of excitations are found in this region. The reliability of the calculation is examined by means of a sum rule for the spectral weight function. The average and the spread of the spectral distribution are computed.
