We experimentally study 2p photoionization of neon dimers (Ne-2) at a photon energy of hv = 36.56 eV. By postselection of ionization events which lead to a dissociation into Ne+ + Ne we obtain the photoelectron angular emission distribution in the molecular frame. This distribution is symmetric with respect to the direction of the charged vs neutral fragment. It shows an inverted Cohen-Fano double slit interference pattern of two spherical waves emitted coherently but with opposite phases from the two atoms of the dimer.

Abstract
We experimentally study 2p photoionization of neon dimers (Ne-2) at a photon energy of hv = 36.56 eV. By postselection of ionization events which lead to a dissociation into Ne+ + Ne we obtain the photoelectron angular emission distribution in the molecular frame. This distribution is symmetric with respect to the direction of the charged vs neutral fragment. It shows an inverted Cohen-Fano double slit interference pattern of two spherical waves emitted coherently but with opposite phases from the two atoms of the dimer.File in questo prodotto:
