Radial Distribution Function for HCP and FCC lattices

[thepopasmurf]

I was wondering, does anyone have any images that show the difference between the radial distribution functions for hcp and fcc lattices? I would be useful for reference purposes.

With the ideal ratio c/a, surely no difference.
But no real metal has this ideal ratio when hexagonal. Maybe cobalt ?
So as many histograms as metals - and alloys...

Maybe you can adapt the speadsheet I made for predicting the diffractogram peaks for any simple lattice, here for chlorite :

The main adaptation you have to do is to use the direct metric tensor, rather than the reciprocal metric tensor.
It will save you hours and hours of work.
