Why is the gradient of the voltage potential field not equal to the electric field?Login
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.

electric potential n. The work per unit of charge required to move a charge from a reference point to a specified point, measured in joules per coulomb or volts. The static electric field is the negative of the gradient of the electric potential. ...
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...
The electric potential (in volts), defined as the work done in bringing a unit of positive charge from infinity to that point, can be derived from Maxwell’s equation and is related to the electric field, as shown in Equation 12.3; [12.3]−∇ϕ=E where ϕ is the electric ...

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, ...
Objective To calculate the electric field and potential distribution of multi-needle electrodes in conductive media(biological tissues) by integral equation approach. Methods According to the electric potentials of multi-needle electrodes, discrete equations based on unknown linear current density were establ...
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...
