  We have studied the correlation potentials produced by various adiabatic
connection models (ACM) for several atoms and molecules. The results have been
compared to accurate reference potentials (coupled cluster and quantum Monte
Carlo results) as well as to state-of-the-art ab initio DFT approaches. We have
found that all the ACMs yield correlation potentials that exhibit a correct
behavior, quite resembling scaled second-order G\"orling-Levy (GL2) potentials,
and including most of the physically meaningful features of the accurate
reference data. The behavior and contribution of the strong-interaction limit
potentials has also been investigated and discussed.
