Bordet theory is a physical model that describes the interaction of two particles on a microscopic scale. It was developed by French physicist Jacques Bordet in 1965 and was an important step in the development of quantum mechanics.
Bordet's theory is based on the idea of individual particles that do not interact with each other as long as their speeds and masses remain unchanged. However, when these particles collide, their properties change, which is determined by the law of conservation of energy and momentum.
When two particles collide, they exchange momentum and energy. This leads to changes in their speeds and masses, which can change the speed or direction of movement of each of the particles. As a result, the particles can exchange their momentum, which usually results in elastic scattering.
However, in some cases, particles can transfer their momentum to each other by exchanging energy. This process is called transverse scattering, and it is caused by the cubic terms in the equation of motion. In this case, both particles retain their energy, but change the direction of their movement.
The mechanism of transverse scattering plays an important role in atomic nuclear physics and astrophysics. It is also used to describe processes occurring during high-energy collisions in collider experiments.
Thus, Bordet's theory is the basic concept of interaction between particles in the microcosm. It allows one to describe complex processes occurring during particle collisions and is widely used in various fields of science and technology.
