The electronic states of homonuclear diatomic molecules give rise to double slit like oscillations in the photoabsorption cross section of these molecules, depending whether the electrons are emitted from a randomly distributed or an oriented target. We show this phase shift effect and a transition phenomenon from coherent to randomly oriented target properties unambiguously for the first time for the photoionization of molecular hydrogen.
