[neutron-mc] Bragg's law for single crystals

[Emmanuel Farhi]

I'll have a look at that as soon as I can (probably next week)

Thanks for reporting !

What can easely be done is to check also the Filter_Powder component, that
was designed as a filter but acts as a general powder sample that scatters
everywhere. Then (using for instance the sample files *.dat given in the
version 1.6-ill) you can check the existence of powder lines at expected
angles.
That would also be a good opportunity to look at the intensity scattered by
this compoennt. If you have some diffractometer data for simple powders (the
best would be to have one of these *.dat files), could you compare the
intensity of the simulated lines vs the measured one ?

Any volunteer ?
