• The frequency vs. wave vector dispersion relations for lattice waves travelling along symmetric directions [00ζ], [ζζ0] and [ζζζ] of transition metals molybdenum, tantalum and niobium are calculated according to a model proposed by Sharma and Joshi which includes the effect of conduction electrons on the lattice vibration in metals. The theoretical results are compared with the recently Published experimental dispersion curves obtained from inelastic neutron spectrometry. Tolerable agreement with the neutron spectroscopic data is obtained for molybdenum and tantalum, but not for niobium.
