Hello,

I would kindly like to ask if there is an option to include the isotope substituted phase to refine the neutron data. We collected 7Li, 11B and 2H enriched samples and I am in the process of analyzing the data. However I don't see an option to include the isotope in the PDFgui software. Is there an option to include these isotopes rather than the natural abundance?

Thanks,

Sawankumar Patel

Thanks for the question Sawankumar.  This is discussed a bit already in diffpy-users (search for "isotope").   Most common isotopes are there and you can access them with the pattern 16-O (i.e., that would return the oxygen-16 isotope.
