Resumen:
We present a detailed study of the stability conditions of hydrogen-antihydrogenlike quasimolecules usingboth variational and finite-size scaling calculations. The stability diagram of the nuclear charge Z as a functionof the internuclear distance R shows bound and unbound regions separated by a first-order critical line.Calculations of the leptonic annihilation rate show a peculiar behavior for nuclear charges Z>=2, which was notobserved for the hydrogen-antihydrogen quasimolecule; it goes through a maximum before it decays exponentiallyfor large interhadronic distances. This might have a practical impact on the study of stability of matterantimattersystems.
