Invention of Le Bail fitting and Le Bail Extraction
“came during a long and lonesome night experiment at ILL (Institute Laue-Langevin, Grenoble, France)”
“It seemed so simple that my first thought was that probably either it was already done or it did not work at all. But at least everybody used it successfully for only one cycle when extracting the so-called "|Fobs|" at the end of any Rietveld refinement. These "|Fobs|" being used for RBragg calculation and Fourier difference purposes though it was long recognized that they were biased due to partitioning according to the Fcalc, hence the quotes.”
