In order to illustrate how the nonlocal EDF derives from a finite-range pseudopotential, we show explicitly the functional obtained from the averaging of the zero-order finite-range pseudopotential over the nuclear Slater determinant. Below, symbols and denote, respectively, the order- regularized pseudopotential and functional.
The four terms of the pseudopotential at zero order are,
The complete expression for the zero-order nonlocal EDF obtained
from (16) reads
