Gauge symmetry, left-right asymmetry and atom-antiatom systems:   Coulomb's law as a universal molecular function
  We show that Coulomb's law is a universal molecular function. Charge inversion in one atom (handedness or chirality) generates a switch from atom-atom to atom-antiatom systems. this switch reduces the 10 term Hamiltonian for 4-particle systems to only 1 or 2 terms. This reduced parity adapted Hamiltonian accounts for observed PECs for atom-atom systems (results for 9 bonds are given). Hydrogen-antihydrogen reactions, feasible in the near future, will produce a normal H(2) molecule, which would solve the problem about the existence of anti-matter.
