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.
