The electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small relative to the mass of the proton, a hydrogen reservoir is basically a proton reservoir. Many other subatomic particles (elemental or composite) may be produced in elementary processes that occur in nature or in the laboratory. In various physical applications of elementary particles, it is necessary to know the rotation speed around the own axis of an elementary particle in motion. The work determines this angular velocity of rotation of the particle with a very high accuracy depending on its known linear displacement velocity. In other words, the angular velocity of an elementary particle is in the function of its linear displacement velocity, also obtained by De Broglie's hypothesis that the impulse of the elementary particle is preserved. Applications of this new theory can be used in nuclear power, in nuclear fusion and in high-power laser physics. Of the desire to add a new brick to the physical construction of nuclear fusion reactor theory, to obtaining sustainable nuclear energy, but also to the optimal realization and to the other possible applications, one presented this original work.
