Engineering Physics Annotation << Back GENERATION OF PHOTON BY THE EXCITED ATOM S.I. IGOLKIN The generation of a photon by an excited atom occurs in a fi nite time-dependent process of rearrangement of internal stress fi elds around an electron that changes its orbit. Radiation of light has close analogies with the generation of vortex structures in a continuous medium and is adequately refl ected in the framework of traditional, non-quantum mechanics. Power, energy characteristics of the electron transition between the terms of the atom in the regime of self-oscillations with the emission of a photon are considered. An analysis is made of the transformation of the initial angular momentum of the electron into the spin of the emitted photon with the formation of a new angular momentum due to the work of the nuclear fi eld. From the frequency and energy dependences, estimates of the geometric dimensions of the optical photon are obtained. Key words: optical photon, generation process, transformation of orbits, reaction of the medium, frequency dependences, field physics, stability of quanta.
