[en] The full three-order and quasi fourth-order perturbation formulae for the EPR trigonal symmetric g_i-value of the ground state ³A₂ of d⁸ configuration have been derived under the assumption of strong field approximation. Using this formula, the μkα-correlation field model and d-orbital theory suggested by Zhao, the g-factor for a number of compounds, namely, RbNiCl₃, NiCl₂, (CH₃)₄NNiCl, CsNiBr₃, NiBr₂, (CH₃)₄NNiBR and RbNiBr₃ has been calculated without any adjustable parameter. Our theoretical results agree well with the experimental findings. (author). 7 refs, 1 tab

[en] The simple on-top site random-deposition model for film growth on a simple-cubic (100) substrate is extended to other adsorption-site geometries and crystal structures. Nontrivial statistical correlations within the growing film typically result. However, the master equations can be solved exactly to elucidate, e.g., growth kinetics, Bragg intensity (I/sub Br/) behavior for surface diffraction, and spatial correlations within the film. Other techniques facilitate analysis of the percolative structure of intralayer islands. For random deposition at fourfold hollow sites on a face-centered cubic (100) substrate, despite the absence of diffusion, there are distinct I/sub Br/ oscillations similar to those observed experimentally during deposition of Pt on Pd(100) at low temperature
