Solvability of the problem about transversal oscillations of a rectangular elastic membrane for the case when the membrane was subjected to a dynamic impact in one point is investigated. The symmetry group of the Mendeleev periodic element system. A dynamic justification of using the representations of the dynamic symmetry group of a hydrogen-like system is offered for the mathematical description of the symmetry properties of Mendeleev's periodic system of elements. The contents of the multiplets is fully compatible with the experimentally observed contents of the electron shells of atoms. Kuvshinov V. I., Sinitsyn N. A., Shulyakovski R. G. Study of the correlation moments as new criteria for the installation channel of deep inelastic scattering.
Quasiclassical approximation gives trivial results.
If we take into account the first quantum correction, then the moments have a special form. Thus, we have obtained new features of instanton induced events in addition to the known footprints, which can be used for experimental search of these processes. The influence of excitation on the changing thermodynamic functions of cellulose is analysed. Co 60 is caused by some main defect taking part in carrier removal scattering charge state alteration. E C - 0.12 eV is found.
