BornAgain-git-main Custom formfactor

Scattering from a monodisperse distribution of particles, whose form factor is defined by the user.

This example shows how users can simulate their own particle shape by implementing the analytical expression of its form factor.
The particular shape used here is a polyhedron, whose planar cross section is a “plus” shape with a side length of $20$ nm and a height of $15$ nm.
These particles are distributed on a substrate.
There is no interference between the scattered waves.
The wavelength is equal to 0.1 nm.
The incident angles are $\alpha_i = 0.2 ^{\circ}$ and $\varphi_i = 0^{\circ}$.
