Magnetic Multipole Moment And Silver Nanostructure Of The Substrates

The theoretical and experimental studies for highly ionized atoms have developed fast in recent years. The studies of structures and spectral data for highly ionized atoms are on the theoretical front.By Grant Multi-configuration Dirac-Fock Code with Breit and QED corrections, three configuration and Feimi distributation and AL model, we calculate systermically magnetic dipole M1, magnetic quadrupole M2, magnetic octupole M3spectral transition wavelengths, transition probabilities and oscillator strengths for Be-like ions, using six electron configuration, we calculate systermically magnetic dipole M1, magnetic quadrupole dipole M2, magnetic octupole M3spectral transition wavelengths, transition probabilities and oscillator strengths for Mg-like ions, The datas are necessarily for atomic spectra, laser plasma, MCF and ICF. It is important to study those materials such as Al, Ti, Fe, Cu, Ge, Mo, Au, Pb,U etc. It has very strong applied background in some regions.Silver nanostructures on the surface of glass substrate have been synthesized by small gold seeds with the assistance of Na3-citrate. The effect of surface morphology of thin films of silver nanoparticles degree on the SERS activity of the substrate was studied by transmission electron microscopy, scanning electron microscopy and UV-Vis spectroscopy. The results showed that the silver nanostructure of the substrates which finally grew up to110nm16hour irradiation took on irregular shape, and some of nanoparticles stacked to form bilayer. A new broad band appeared in the absorption spectra of the substrates due to the interparticle dipole-dipole coupling of surface plasmon resonance response of the triangular silver nanoplate particles, which red shifted600-813nm as the particles grow up, indicating the intensification of the coupling. The strongest SERS signal of SERS-Active Substrate was fabricated after12h.
