Abstract
The exotic hydrogen-antihydrogen molecule and its properties are investigated. The system is metastable due to matter-antimatter annihilation, but also due to the possible double autoionization process describing the decay into protonium and positronium. The latter decay channel is energetically favored at small internuclear distances where the protonium dipole cannot permenently bind positronium. The leptonic density and reduced one-particle density matrices are calculated and discussed for the ground and the first excited state.
