The point made by Armel is possibly misplaced. Whilst I agree that waiting for neutron data does impose a considerable delay when compared against readily available laboratory X-ray facilities, this misses the point somewhat. In the cases Jaap outlined an X-ray diffraction experiment would be

OK to follow up Andrew's remarks: I use simultanous X-ray and neutron refinements almost all the time nowadays. There are a lot of advantages when you like me work with transition metal oxides: 1) in general the refinement is more stable. 2) the possibility the study much more complicated str
