Hi
could anyone help with a simple crystallography question.
I am studying domain growth in crystals via Monte-Carlo simulations of atomistic models. I am writing a program to simulate the (neutron ) scattering pattern from a data-file of atomic positions via the rather brute force method of summing the scattered wave intensities at each point on a detector.
If I want to generate a pattern from a particular orientation – say 4,2,0 planes. Should the incident beam be perpendicular to the desired plane with the detector at some distance perpendicular to the incident ray or should the beam be at some arbitrary angle such as 1,1,0 with the detector oriented at 4,2,0 ?
Any suggestions very gratefully received
