Abstract:Based on macroscopic QED in linear, causal media, we present a consistent theory for the Casimir-Polder force acting on an atom positioned near dispersing and absorbing magnetodielectric bodies. The perturbative result for the van-der-Waals energy is shown to exhibit interesting new features in the presence of magnetodielectric bodies. To go beyond perturbation theory, we start with the center-of-mass equation of motion and derive a dynamical expression for the Casimir-Polder force acting on an atom prepared in an arbitrary electronic state. For a non-driven atom in the weak coupling regime, the force as a function of time is shown to be a superposition of force components that are related to the electronic density matrix elements at chosen time. These force components depend on the positiondependent polarizability of the atom that correctly accounts for the body-induced level shifts and broadenings.

“…1 it can be concluded that the coverage at the maximum in resistivity can be used for the evaluation of the monolayer coverage as well as the BET isotherm and the minimum in the change in work function. The resulting roughness factor for a Ni film of 13.6 nm thickness annealed at 373 K for one hour was 2.6 ± 0.1 (area ofaXe adatom Axe = (0.171 ± 0.OO4)nm 2 [12][13][14]).…”

The adsorption of H2 on CO‐covered Ni films was investigated in the temperature range of 77 to 273 K by means of measuring the change in resistivity, the change in work function, isotherms and isosteric heats of adsorption. – At 77 K molecular H2 is only physically adsorbed on a CO covered Ni film with a minor increase in resistivity. H2, atomised by a hot tungsten filament, is readily adsorbed on a CO layer at 77 K, the accompanying change in work function is −1.45 eV. – Molecular H2 is adsorbed on a CO‐covered Ni film in the temperature range of 180 to 273 K with a decrease in resistivity and a temperature dependent decrease in work function. The maximum change in work function is −80 mV at 185 K and 5 · 10−2 Pa. The initial isosteric heat of adsorption of H2 is 36 ± 2 kJ/mol, which decreases slowly with increasing coverage.

“…While the shape of the 5p3,, signal (split or unsplit) is an unambiguous qualitative indicator for the presence or absence of 2D solid xenon islands on the surface, most probably of 2D close-packed Xe(ll1) structure [20], the decomposition of the spectra provides a quantitative measure of the concentration of both coexisting 2D phases. This is an advantage over the He scattering experiments [4] as well as the ARUPS derived band dispersion [6,12], which are sensitive to the condensed phase only.…”
