Abstract
In the framework of a variational method, the molecular ion H +2 in a magnetic field is studied. The optimal form of the vector potential corresponding to a given magnetic field (gauge fixing) is chosen variationally. It is shown that for any magnetic field strength, as well as for any orientation of the molecular axis, the system (ppe) possesses a minimum in the potential energy. The stable configuration always corresponds to the elongation along the magnetic line. However, for magnetic fields B≳2×1011 G and some orientations, the H +2 ion becomes unstable, decaying into the H atom +p.
