Tunneling dynamics of a two-atom system

G. A. Muradyan, H. R. Hakobyan, A. Zh. Muradyan

We discuss the quantum tunneling of a diatomic molecule, concentrating on the transmission differences corresponding to different internal states. The evolution picture is constructed basing on introduction of notion of effective potential, the form of which is dependent on interatomic separation. To fully treat the tunneling problem analytically, we slightly modify the effective potential for each internal state. Clear splitting of these resonances enables us to suggest a scheme of molecular interferometer working as a Earth gravity sensor.
