title: Interference effects in the resonant photoemission channels to the Ne+ 2p(4)(1D2)3p 2P, 2D, and 2F states in the Ne 1s excitation region.
abstract: We present measurements of total and partial photoionization cross sections of Ne in the 1s excitation region. The total cross section exhibits resonances with symmetric profiles, whereas the branching ratios to the Ne+ 2p(4)(1D2)3p 2P, 2D, and 2F 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.
