L.Martín-Marero, D.Chahid, A.Senger, G.Ristig, M. L.16 págs.; 13 figs.The collective dynamics of liquid deuterium is studied by means of inelastic neutron scattering (INS) at 20.14 K and under 2 bars of applied pressure using two different incident energies. The low-incident-energy (high-energy-resolution) spectra are studied in detail by means of a time-of-flight (TOF) technique, whereas the finite-frequency response is investigated using a higher incident energy on a triple-axis spectrometer (TAS). The main finding of our work is the observation by the latter experimental technique of well-defined collective excitations up to a momentum transfer of 3.8 A-1. Comparisons are established with the dispersive behavior observed in other liquid systems as well as with the predictions from recent correlated-density-matrix calculations. © 1993 The American Physical Society.This work has been supported in part by DGICYT Grant No. PB89-0037-C03 and by the Deutsche Forschungsgemeinschaft under Grant No. Ri 267/16-1.Peer ReviewedAmerican Physical SocietyGerman Research FoundationMinisterio de Educación y Ciencia (España)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2016201619932016info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/140044reponame:DIGITAL.CSIC.
