Atomic densities from Slater's rules #87

Open susilehtola opened 11 months ago

Slater's rules offer a simple way to compute somewhat realistic atomic electron densities. They are also used in the formation of some quadrature grids. The rules used in Molpro have been summarized in J. Chem. Phys. 149, 044103 (2018); in addition, one needs to assign formal occupations to the orbitals.
