Abstract
Longitudinal acoustic phonons have been measured by coherent inelastic neutron scattering in the direction of the platinum chains of a single crystal of the one-dimensional conductor Pt ·3O at room temperature. The phonon dispersion curve shows a pronounced anomaly at the phonon wave number and is interpreted as the logarithmic Kohn anomaly characteristic of a one-dimensional metal.
