- Abstract
A closed formula for the state-resolved photodetachment probabilities of an electron from a weakly bound complex of an atomic anion with a diatomic molecule residing in a nondegenerate electronic state is obtained. Due to the reduction of the dipole moment matrix elements in terms of molecular electronic wave functions to the matrix elements in terms of atomic wave functions, the formula allows one to calculate the relative intensities of the photoelectron spectrum taking into account rovibrational and spin-orbit interactions and using practically convenient representations of the wave functions of the bound initial state of an anionic complex and of the bound or unbound final state of a neutral system. The methods of estimation of the atomic dipole moment matrix elements, the error due to neglect of the photoelectron rescattering, and possible modifications and generalizations of the formula are discussed.
