Some Analyses of Atmospheric Electric-Field Gradients
The earth maintains surprisingly large voltage gradients, Ez [V/m], between its surface and a conductive ionosphere above 100 km, with fair-weather measurements averaging about 160 V/m near the surface, positive upwards. These gradients are easily detected but difficult to quantify with accuracies better than a few percent. Data records survive from several sites dating to the early 1900's. Mea...
متن کاملMeasurement and Calculation of Electric Field Gradients in Hg-Mercaptides *
Electric field gradients (EFG) at Hg were determined in mercury mercaptides H g ( S ( C H 2 ) i C H 3 ) 2 experimentally for i e {0, 1, 2} using time differential perturbed angular correlation and theoretically for i e {0, 1} with the full potential linearized augmented plane wave code WIEN95. Due to the large unit cells and small hydrogen atoms not full convergence of the plane wave basis set ...
متن کاملSIGN DETERMINATION OF THE 57Fe ELECTRIC FIELD GRADIENT IN AMORPHOUS Al70Si17Fe13
In amorphous A170Si17Fe13, a fraction p+ 2. 0.50 of iron atoms have a positive electric field gradient (EFG), After crystallization, p+ increases strongly while the mean quadrupole splitting and isomer shift show almost no change. The results are interpreted with the help of EFG models. I INTRODUCTION Melt-spun aluminium-based amorphous alloys have been recently described in Al-transition metal...
متن کاملFully relativistic coupled cluster and DFT study of electric field gradients at Hg in 199Hg compounds.
We investigate the magnitude and interplay of relativistic and electron correlation effects on the electric field gradient (EFG) at the position of Hg in linear and bent HgL(2) (L = CH(3), Cl, Br, I) and trigonal planar [HgCl(3)](-) compounds using four-component relativistic Dirac-Coulomb (DC) and non-relativistic (NR) calculations at the Hartree-Fock (HF), DFT, MP2 and coupled cluster (CC) le...
متن کاملElectric Field Gradients at the In Site in Au-In Compounds *
Interface compound studies on the Au-In system [1,2] have shown that Auln 2 is formed below and around room temperature. Auln2 exhibits a CaF2 structure of cubic symmetry leading to a vanishing electric field gradient (EFG) at the lattice sites. Application of the perturbed angular correlation (PAC) method to detect the other intermetallic compounds formed in the interface region at elevated te...
