Admixture diffusion processes with their cascade decay in a multicomponent body is investigated. For the specific scheme of decay, coupled initial-boundary value problems of diffusion of the cascade type are formulated, their solutions using Green functions are obtained. Software modules are developed and numerical analysis of functions of both decaying particle concentration and mass flows of decaying substances is carried out. It is shown that on the zero stage of decay the function of substance concentration incoming from the layer surface is a monotonically decreasing function those time-increases till gets on the steady-state regime. In the case of concentration distributions on next stages of decay, near-surface increase of the function is observed; its maximum grows up and shifts to depth of the body. Figs.: 9.

Photon is a compact formation, where effective force reduces the configuration. The structure of elementary particles is determined on the basis of the rotating and precessing photon. Photon is a bunch of electromagnetic field, all parts of which are moving at the speed of light. When moving along the circle not all parts may move at this speed in result of which an electrostatic field appears. Photon and elementary particles have the smaller size, the greater their mass-energy. The electron has the largest size. Neutron, as well as the atomic nucleus consists of protons and negative fields. It is determined the structure of the neutrino, mechanism of the particle charge identity, energy fields. The unified field theory cannot be created because of the large difference in the fields. Figs.: 9.
