CCL: Computation of density gradients on Lebedev grids



 Sent to CCL by: "Rick Muller" [rmuller=sandia.gov]
 
Can anyone point me to a reference for the calculation of density gradients on Lebedev grids? I suspect that one computes the multipole moments of the density and gets the gradients from there, but I haven't actually ever found a reference for this, and would be interested in seeing one.
 Thanks in advance,
 Rick
