Orientation Effect

Could use a paragraph or two on preferred orientation effect

Hölzer paper

This paper for wavelength needs to be cited properly and "Hölzer - Ka1,2 and Kb1,3 x-ray emission lines of the 3d transition metals" presents different values than given in the table here. Furthermore, the new Tables for Crystallography contain Hölzer's values. —Preceding unsigned comment added by 140.181.106.46 (talk) 18:42, 21 February 2011 (UTC)

Does anyone know what the "weights" are in the weighted averages? For example, I see that the relative intensity for Cu Kα2/Kα1 is 0.52. I was wondering if we simply use (0.15405929 + 0.52*0.15444274)/1.52 ≈ 0.1541905 nm as the weighted average of Cu Kα. --D昌양 (Talk) 16:21, 1 July 2024 (UTC)

Assessment comment

The comment(s) below were originally left at Talk:Powder diffraction/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

My comment is that the page is a reasonable general description of a pretty widespread technique. It may need some more straightening particularly on the peak broadening section. Jcwf 00:37, 17 September 2007 (UTC)

Gandolfi camera

Some mineral articles mention powder diffraction using Gandolfi cameras. Also New technique enables mineral ID of precious Antarctic micrometeorites says "In the late 1960s, a Gandolfi x-ray diffraction camera that could rotate on two axes began to be used within X-ray crystallography". I don't want to copy those words or risk paraphrasing. Could we mention them near the start of the camera section? - Rod57 (talk) 16:18, 31 July 2020 (UTC)

Split x-ray diffraction from x-ray crystallography

I propose splitting X-ray diffraction out of X-ray crystallography, discussion started at Talk:X-ray crystallography#Split x-ray diffraction and crystallography. The two are not the same, and there are many areas of XRD where the focus is not on detailed determination of atomic positions. Examples are powder diffraction where comparison is made to known samples, SAXS and many more. There are many areas/pages where it is relevant to say "use XRD" but wrong to say use "X-ray crystallography This would also help to improve the current rambling X-ray crystallography page. Comments to the X-ray crystallography talk page please. Ldm1954 (talk) 07:50, 14 April 2024 (UTC)
