tensor of electric-field gradient
1Electric field gradient — Mathematically, the electric field gradient (EFG) is the hessian matrix (the matrix of the second derivatives) of the electrical potential V: :V {ij} = frac{partial^2 V}{partial x i partial x j}It is an important structural property of a… …
