Analytical Schwartz Density Applied to Heavy Two - Electron Ions
نویسندگان
چکیده
Ž . An analytical expression of the electron density function r r due to Schwartz for two-electron atomic systems is applied to a detailed study of density-dependent properties of relatively heavy two-electron ions. Comparison of the Schwartz results with those from accurate Hartree]Fock and Hylleraas wave functions shows that despite its simple yet analytical form, the Schwartz density has a quantitative applicability in the density study of two-electron atoms within the nonrelativistic framework.

Heavy metals removal from wastewater by using different kinds of magnetite nanoadsorbents: effects of different organic and inorganic coatings on the removal of copper and lead ions
Co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of Pb(II) and Cu(II) toxic metal ions from wastewater samples. Prepared nanoadsorbents were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The average sizes of t...

High resolution Auger-electron spectroscopy has been applied to the interaction of swift heavy ions with atomically clean metallic solids. Spectra have been taken for fast projectile electrons and for charge-state equilibrated ions at normal incidence on micro crystalline beryllium samples, Al(100) single crystals and several metallic glasses (Al87La7Ni5Zr1, Ni78B14Si8, Co66Si16B12Fe4Mo2).
