Dear Rietvelders,
There is two things I would like to ask.
1. Physical interpretation of selective peak broadening
I have a difficulty in interpreting selective peak broadening in my TOF data
of quaternary Heusler alloy.
All peaks for all-odd hkl reflections show significant broadening (about
Dear Kotaro,
The broadening you describe seems to be due to a non-uniform distribution of
site occupancies in the crystal lattice. A general model for such
defect-related broadening is described here:

The model is included into the DDM program (but
Dear Kotaro,
The same rule of line broadening was observed in beta phase of Mg(BH4)2, and
was explained as ordering of twin domains, in other words microtwinning which
creates a superstructure to the even,even,even subcell. If the twinning
probability is not 100%, then the odd,odd,odd
