Abstract Closed-shell atoms scattered from a metal surface exchange energy and momentum with surface phonons mostly via the interposed surface valence electrons, i.e., via the creation of virtual electron-hole pairs. The latter can then decay into su

The surface phonon dispersion curves of ultrathin (3–6 ML) Pb layers grown on Si(111) and Ge(111) substrates, measured with inelastic He atom scattering, reveal shallow Kohn anomalies in the surface acoustic branches. Ab-initio calculations based o

He atom scattering has been shown to be a sensitive probe of electron-phonon interaction properties at surfaces. Here it is shown that measurements of the thermal attenuation of the specular He atom diffraction peak (the

The electron-phonon coupling parameter for a dense phase of a 4/3-monolayer of Pb on Si(111) is derived from the temperature dependence of He-atom scattering (HAS) reflectivity upon cooling from the high-temperature (1 × 1) to the low-temperature (3

The Geyser effect in the expansion of solid helium into vacuum

Autor: P. Nieto, Giorgio Benedek, J. P. Toennies

Publikováno v: The European Physical Journal B. 76:237-249

The mechanism behind the intensity oscillations accompanying the flow of solid helium through a micron-sized orifice into vacuum, called the geyser effect, is investigated by measuring the pressure pulses at various locations in the entire flow syste

Publikováno v: The European Physical Journal D. 56:353-358

The path integral Monte Carlo calculated radial distributions of para-hydrogen clusters (p-H2)N consisting of N =4 −40 molecules interacting via a Lennard-Jones potential at T =1 .5 K show evidence for additional peaks compared to radial distributi

By means of quantum mechanical simulation of the reaction F + H2(v = 0; j = 0, 1, 2) → H + HF(v′, j′) on the Stark-Werner ground state potential energy surface at collision energies of 1.84, 2.74, and 3.42 kcal/mol, we have analyzed interferenc

The special features of rotationally resolved differential cross sections of the F + H2 reaction at small scattering angles

Autor: J. P. Toennies, L. Yu. Rusin, Mikhail B. Sevryuk

Publikováno v: Russian Journal of Physical Chemistry B. 2:452-464

We studied the nature and collision energy dependence of the maximum that appears in the angular distributions of the HF (v′ = 3) product of the F + H2 (v = 0; j = 0, 1, 2) → H + HF (v′, j′) reaction at small scattering angles θ in the cente
