Query: Antisymmetry in hydrogenic HH+ and antihydrogenic antiHH+ cations:
  classical and ab initio quantum mechanical calculations   Ab initio quantum chemistry reveals how the charge-antisymmetric
antihydrogenic antiHH+ state, deriving from conventional positional
antisymmetry of a 3-unit charge system, is hidden in the PEC (potential energy
curve) of the molecular hydrogen cation. Only with internal charge inversion
and Coulomb's law, the anti-symmetry generated by positional coordinates can be
understood but this solution was persistently overlooked. Stabilizing
matter-antimatter interactions not only exist in nature, they are an essential
element, even in wave mechanics, for explaining stable composite matter with a
Coulomb model.
