We study tunneling exits of H2^＋ at large internuclear distance in strong laser fields by numerically simulating the time-dependent Schrodinger equation plus a classical backward propagation of the ionized wave packet. This study strengthens the understanding of molecular tunneling ionization in strong laser fields.展开更多
