This paper reports elastic and inelastic neutron-scattering studies on the incommensurate linear-chain mercury compound . The one-dimensional phonon dispersion curve associated with the randomly phased linear Hg chains has been measured at room temperature. A transition, at 120 K, from a randomly phased interchain structure to a "phase-ordered" structure has been found and characterized.
