| Abstract: | The orientation-dependent single ionization rate of the diatomicmolecular ion H$_2^+$ with different active orbitals in an intensefield is studied by using S-matrix theory. Our results show thatthe orientation-dependent single ionization probability of H$_2^+$is greatly dependent on the symmetry and the electron densitydistribution of its initial states, and it can be used to identifythe excited state of the molecular ion in the dissociation process. |
