  • Collective Excitations in Ethane Monolayers Adsorbed on Graphite (0001) Surfaces 

    Hansen, Flemming Y.; Wang, R.; Taub, Haskell; Shechter, H.; Reichel, D. G.; Danner, H. R.; Alldredge, G. P. (American Physical Society, 1984)
    Inelastic incoherent neutron spectra below 4.1 THz have been obtained for the √3×4 "herringbone" and √3×√3 "on-end" monolayer phases of ethane adsorbed on graphite basal planes. One-phonon cross sections calculated ...

  • Intramolecular and Surface Vibratory Modes of Butane Adsorbed on Graphite Observed by Inelastic Neutron Scattering 

    Taub, Haskell; Danner, H. R.; Sharma, Yadunandan Prasad, 1945-; McMurry, H. L.; Brugger, R. M. (American Physical Society, 1977)
    Inelastic and elastic neutron scattering have been used to study the dynamics and structure of butane (C4H10) adsorbed on a graphitized carbon powder at 77 K. In addition to the intramolecular vibrations found in the bulk ...

  • Structure and melting of submonolayer ethane films on graphite 

    Coulomb, J. P.; Biberian, Jean-Paul; Suzanne, J.; Thomy, A.; Trott, Gary J. (Gary John), 1952-; Taub, Haskell; Danner, H. R.; Hansen, Flemming Y. (American Physical Society, 1979)
    Elastic neutron diffraction has been used to study the structure and melting of submonolayer ethane films physisorbed on exfoliated graphite. Analysis of the relative intensity of seven Bragg reflections of the film yields ...
