Critical Analysis of Non-Nuclear Electron-Density Maxima and the Maximum Entropy Method

R. Y. de Vries, W. J. Briels, D. Feil
1996 Physical Review Letters  
It is shown that the non-nuclear maxima reported for silicon are artifacts of the maximum entropy method that was used to analyze the x-ray diffraction data.  ...  We report systematic tests of the improved method leading to the absence of non-nuclear maxima in Si. Likewise, the non-nuclear maxima reported earlier in beryllium are not substantiated.  ...  The traditional way to extract the EDD from a limited set of noisy data is to fit the structure factors by a model.  ...

The prior in the maximum entropy method. Do non-nuclear maxima in Be and Si exist?

R. Y. de Vries, W. J. Briels, D. Feil

No non-nuclear maxima were observed in this density. When the MEM was applied on the structure factors calculated from this density non-nuclear maxima appeared in the Si-Si bond.  ...  On the other hand, these non-nuclear maxima could also be an artifact of the MEM. We have tested the MEM on data calculated from a known EDD of silicon.  ...  No non-nuclear maxima were observed in this density.
