For elements of low atomic number, the nonrelativistic Schrdinger Hamiltonian is commonly assumed. One of our principal interests concerns the difference between results calculated on the basis of the Dirac, relativistic Hamiltonian from those calculated nonrelativistically. Before proceeding to that topic...
This analysis aids in understanding how the introduced elements influence the material's reactivity and sensitivity towards H2S, thus guiding the development of effective gas sensor applications. Knowledge from literature review showed that in the interaction between the modelled hybrid materials, the HOMO...
摘要: The orbital electronegativities of the neutral atoms of the A elements of rows three and four and of the monopositive ions of periods one and two are reported and briefly discussed.DOI: 10.1021/j100801a024 被引量: 86 年份: 1963 ...
and the imaginary part describing their inverse lifetimes. The significant components of the self-energy are spin diagonal, considering that the contribution of the off-diagonal elements is negligible for the investigated C3v-symmetric adatom-substrate systems (see Supplementary Note1). These quantities...

Chlorine-36 is widely used forgeological surface exposure dating because it is produced at measurablelevels from the three main target elements in limestone: Ca, K and Cl. Theproduction rates of36 Cl in limestone samples depend on the interactionsof the cosmic-ray neutrons with the40 Ca and ...
It has been found that the gas-phase diffusion of gallium and phosphorus atoms into silicon provides not only the compensation but also partial interaction of the elements with each other. Analysis under a scanning electron microscope has shown that, after diffusion and surface treatment, gallium ...
The definition of the the effective correlation matrix elements d i a j b = 2 ( 2 g i a j b − g i b j a ) / ( ϵ i + ϵ j − ϵ a − ϵ b ) allows to define an effective second-order ρ 2 eff density as ρ 2 eff ( r 1 , r 2 ) = ρ 2 HF (...
