The change in character of the even z-parity states from antibonding to bonding in the H +2 ion by strong magnetic fields

Abstract

Using an adiabatic method, the total energies and equilibrium internuclear separations of the even z-parity states δ g, φ u, γ g, and η u of a H + 2 ion in strong magnetic fields ≈ 2.35 × 10 8 T are calculated. It is concluded that any even z-parity state of the H + 2 ion will become the corresponding stronger bonding state with increase of magnetic field strength, even if it is originally in an antibonding state at zero magnetic field.
