Der Kaiser und sein Gott
In his reconstruction of the process and motivation of Constantine`s adoption of Christianity, the author proposes a number of new individual aspects. He commences with an analysis of theearliest testimonials bythe Emperor himself after his conversion, his massive moral and material support for the Christian clergy and ecclesiastic communities, andConstantine`srole as the first ruler of all Christendom up to his death in 337. Finally, it is shown that the Emperor wanted to suppress non-Christian religions and make Christianity the sole religion of the Empire and all humanity
Discrete-row growth of xenon adsorbed on the vicinal Pt(997) surface: Comparison between theory and experiment
Xe exhibits a discrete-row growth mode on the vicinal Pt(997) surface by sequential attachment to the substrate steps. In order to interpret experimental results obtained by grazing incidence helium scattering, potential calculations are performed. A mean-field Hamiltonian within the two-dimensional Ising model is shown to explain the sequential-row growth observed in helium-atom diffraction studies. More specifically, the calculated temperatures for the occurrence of each row depend mainly on the shape of the potential increment due to the steps and countersteps. They are in good agreement with the experimental values associated with maxima in the scattered He intensity versus coverage curves
