Question

which unit cell to use for dynamic structure factor in neutron scattering?

Answer 1

Hey mate!


One thing to note is that you are not using the primitive cell, which is obtained by taking the lattice vectors joining your A atom to the A atom diagonally down and to the right and from the original A atom diagonally up and to the right, such that the A atoms sit at the lattice points, and the B atom sits in the space between.

Thanks for the question!
