For charged three-body systems, we discuss the configurations and orientations that are admissible for given values of conserved total energy angular momentum. The discussed on a configuration space is reduced by translational, rotational dilation symmetries systems. We consider examples systems helium atom (two electrons nucleus) compound two one positron. comparison, well known example Newton...
