SIR 97 is the integration of two programs, SIR 92 and CAOS , the first devoted to the solution of crystal structures by direct methods, the second to refinement via least-square...
Abstract A series of pure and mixed chromium standards has been analysed by x‐ray photoelectron spectroscopy in order to obtain a sufficiently homogeneous and self‐consistent se...
Electron-density maps are calculated by Fourier syntheses with coefficients based on structure factors. Diffraction experiments provide intensities up to a limited resolution; a...
