  We have derived a new method which allows to compute the full and the Pauli
reference kinetic potentials for atoms and molecules in a real space
representation. This is done by applying the optimized effective potential
(OEP) method to {the} Kohn-Sham non-interacting kinetic energy expression.
Additionally, we have also derived a simplified OEP variant based on the common
energy denominator approximation which has proven to give much more stable and
robust results than the original OEP one. Moreover, we have also proved that at
the solution point our approach is formally equivalent to the commonly used
Bartolotti-Acharya formula.
