For an A ‐particle quantum system in a state Ψ, the movement of any pair of particles is studied. Using the corresponding two‐body densities, the effective potential that determines the relative and center of mass movements of the pair of particles is built. Some aspects of the proposed general procedure are applied to different, functions used to describe the ground state of the helium atom. © 2000 John Wiley & Sons, Inc. Int J Quant Chem 79: 75–81, 2000
