S-matrix study on alignment dependence of single ionization of molecular ions with different active orbitals

doi:10.1088/1674-1056/19/6/063302

Abstract The orientation-dependent single ionization rate of the diatomic molecular ion H$_2^+$ with different active orbitals in an intense field is studied by using S-matrix theory. Our results show that the orientation-dependent single ionization probability of H$_2^+$ is greatly dependent on the symmetry and the electron density distribution of its initial states, and it can be used to identify the excited state of the molecular ion in the dissociation process.

Keywords: alignment molecule ionization probability molecular orbits
