Semiclassical study of the one-dimensional hydrogen molecule.
The hydrogen molecule, as a restricted four-body problem, is a mixed chaotic system and is studied in this work as an extension of the helium atom. Several types of one-dimensional periodic orbits have been studied for this two-fixed-center system starting from some known orbits for the one-fixed-center system (helium atom). The hydrogen molecule has been studied by means of a semiclassical formalism. The single quantization of some periodic orbits are shown. These orbits are used to form a global quantization of the hydrogen molecule. Electronic energies of this nonintegrable molecular system are obtained with nonsingle semiclassical quantization.
