| Abstract: | Neutron diffraction exhibits a superstructure peak of krypton adsorbed on graphite, which shifts with coverage. Nevertheless variations in the intensities of the substrate peaks indicates registry. A model is given, grounded on polycrystallinity (antiphases) of krypton mono and bilayer still registered on graphite. The registered phase persists in our sample up to the filling of the bilayer contrary to other results. We think of it as a pinned phase. |
