TL;DR: In this article, the adsorption of H2 on Ni(110) has been studied using He and H2 diffraction and four homogeneous ordered phases as the coverage is increased between 0.7 and 1.6 at a substrate temperature of 100 K were observed.

TL;DR: In this paper, it was shown that the water-formation reaction on Pd(111) has been shown to proceed via a Langmuir-Hinshelwood mechanism via a cosine distribution.

TL;DR: In this article, the reconstructed Au(100) surface has been investigated using He-diffraction techniques and the topmost layer is found to have a dominant (1 × 5) periodicity, whereby the corrugation appears one-dimensional in the direction of the longer unit cell.

TL;DR: In this paper, the adsorption of O2 on Ni(110) at 500 K has been studied using He diffraction, and it was shown that the Ni atoms are aligned in rows parallel to the [001] direction, and that the oxygen atoms are adsorbed at long bridge sites on the surface at a normal distance of ~ 0.3 A above the Ni atom.

TL;DR: In this article, the rotational degrees of freedom are taken into account only in a very rough way in a kinetic equation: the detailed balance relations for the kinetic coefficients in this equation contain rotational partition functions, describing free rotations in the gas phase and assuming totally frozen rotations.
