Kucherenko M.G. NANOBALL DYNAMIC POLARIZABILITY IN THE CASE OF A DEGENERATE ELECTRONIC GAS AND ITS ROLE IN ENERGY TRANSFER PLASMA MECHANISM The author shows how the degeneracy of electronic gas in spherical metal nanoparticles effect on the resonance behavior of the dipole polarizability in monochromatic electromagnetic field on the optical frequencies with dissipative processes in a conductor (complex dielectric permittivity). Frequency dependence of the imaginary and the real parts of polarizability of a spherical nanoparticles are obtained in the form of graphs for different values of particle radius, length of Thomas-Fermievskiyof shielding and damping constant. The author provides expressions for speed radiationless transfer of energy between the molecules in the vicinity of nanoparticles, and rate of energy to it, which include dynamic polarisability on nanoball with a degenerate electronic gas. Key words: polarisability spherical nanoparticles, a degenerate electronic gas, Thomas-Fermievskiy, shielding, energy transfer, plasmons.
