Introduction to collision theory
Collision theory studies an interaction between particles. The theoretical basis of mechanics is the law of conservation of momentum and the law of conservation of energy. The variety of particles makes collision theory divided into: collision of atoms, collision of plasma and so on. Also included are the interactions between particles: the aggregation of light nuclei, the annihilation of positive and negative electrons, the decay of charged pi mesons, the beta decay of neutrons, the interaction of nucleons N and π mesons, the photon gamma and electron e- Of scattering etc.
