The measured interaction frequency is ν Q=730±5 MHz which corresponds to an electric field gradient of | eq|=(1·19±0·05)×10 18 V/cm 2 at room temperature. By considering a second measurement at 4·2°K, which yields the same results as above, and by comparison with available ...
The electric field gradient is simply the change in electric field with direction due to the local distribution of nuclear and electronic charges at a particular point in space in which the nucleus in question is located. From: Encyclopedia of Physical Science and Technology (Third Edition), 2003...
Our calculations suggest that the ultra-high spatial resolution of TERS can be partially attributed to the electric field gradient effect owning to its tighter spatial confinement and sensitivity to the infrared (IR)-active of molecules.关键词: Condensed Matter - Mesoscale and Nanoscale Physics ...
The electric field gradient produced by conduction electrons in the heavy rare earth metals has been calculated taking into account non-spherical effects due to the magnetic ordering in these metals. To our knowledge the values obtained are the first to agree with the sign of the experimental resu...
Molecular properties of the uranyl ion ([UO2](2+)) are studied using both a non-relativistic and a relativistic method. Inclusion of relativity leads to a bond length expansion and makes the electric field gradient (EFG) at the uranium nucleus strongly dependent on the U-O bond distance, ...
Using the first-principles full-potential linear muffin-tin orbital method in the atomic sphere approximation, we have calculated the electronic structure of the intermetallic compound , and evaluated the electric field gradients (EFGs) at all of the three inequivalent positions (two Hf and one Fe...
The electric field gradient tensor, EFGT, of Br-81 and the EFGT's of H-2 were studied by NMR (4.7 T) at room temperature in deuterated single crystals of glycyl-l-alanine hydrobromide monohydrate. eQPHI(ZZ)h-1 (Br-81) is 19.750 MHz, the asymmetry parameter eta(Br-81) = 0.833. ...

Temperature dependence of the electric field gradient at111Cd in Ga- and Bi-metal The quadrupole interaction of Cd impurities in Ga and Bi has been measured at various temperatures by the PAC technique. The results, combined with previous work on pure Ga and Bi, exhibit a considerable influence...
The static electric quadrupole interaction of 111 Cd in the heavy rare metals Gd, Tb, Ho and Er has been studied at room temperature by time differential perturbed angular correlation techniques. From these measurements the effective electric field-gradient, V zz eff , at the Cd-site was derive...
