Electron Flux Distributions in the Photodetachment of H2~-in an Electric Field

The electron flux distributions in the photdetachment of a negative hydrogen molecular ion in an electricfield have been studied by using the two-center model and the closed orbit theory.An analytic formula is presented forthe electron flux of H~-in the presence of an electric field.The results show that the interference between the two orbitspassing through the given spatial point leads to the oscillation in the electron flux distribution.Besides,the interferencebetween the two centers of the H~-is also very important.The comparison between the electron flux of H~-in electric fieldwith the result of H-shows that at the equilibrium distance of two centers in the H~-,the interference of the two nucleion the detached electron’s flux distribution is very strong,while at larger distance of the two centers,the interferenceeffect of the two centers is decreased.
