  Ryabinkin-Kohut-Staroverov (RKS) theory builds a bridge between wave function
theory and density functional theory by using quantities from the former to
produce accurate exchange-correlation potentials needed by the latter. In this
work, the RKS method is developed and tested alongside Slater atomic orbital
basis functions for the first time. To evaluate this approach, Full
Configuration Interaction computations in the Slater orbitals are employed to
give quality input to RKS method, allowing full correlation to be present along
with correct nuclei cusps and asymptotic decay of the wavefunction. The RKS
method will be shown to be an efficient algorithm to arrive at exchange
correlation potentials without unphysical artifacts in moderately-sized basis
sets. Furthermore, enforcement of the nuclear cusp conditions will be shown to
be vital for the success of the Slater-basis RKS method. Examples of weakly and
strongly correlated molecular systems will demonstrate the main features of
Slater RKS.
