Abstract

We present measurements of total and partial photoionization cross sections of Ne in the [Formula presented] excitation region. The total cross section exhibits resonances with symmetric profiles, whereas the branching ratios to the [Formula presented] [Formula presented] [Formula presented], [Formula presented], and [Formula presented] states present strong oscillations in the interresonance regions. We prove that not only the interference between the direct and resonant ionization processes but also the interference among the ionization processes via different nonisolated resonances are important for this effect.
