Re: Rietveld

Argh ! Shame on us three !   But be careful to not confuse an example with a counter-example ;-)   In 1986 had already started the times where Rietveld was so famous that giving his name in the paper was sufficient. You can probably find >20.000 such papers citing the Rietveld method and not

Re: Rietveld

Leonid. Rietveld's code is indeed a specific type of profile refinement. Structure parameters are refined to fit the observed profile intensities using a least squares code similar to that used to fit integrated Bragg intensities at Oak Ridge - ORFLS (1962). From 1961 profile refinement methods
