Analysis of Atomic Collisions
An atomic collision process can be illustrated and classified by its geometry. An atomic particle \(A\) may collide with an atomic particle \(B\). Particle \(A\) propagates in a collimated aligned beam of atoms, ions, electrons or photons. It may then hit particle \(B\) of an atomic target. Often the target \(B\) is also produced by a collimated beam of particles (crossed-beam technique).
