High energy neutrons can collide with atoms and create collisional cascades. These cascades increase the interstitial and vacancy populations. You can simulate the collision between neutrons and other atoms with just the center of mass and the scattering angle. Atom collisions adopt a spherical cross-section
$$\sigma=\pi(2R)^2$$
Where \(R\) is the interaction radius. The flowchart for simulating this is shown below.
