Photoelectron angular correlation pattern in sequential two-photon double ionization of neon

Abstract

We apply an angular momentum coupling formalism to describe the angular correlation pattern in sequential two-photon double ionization of neon. Comparison with previous work (Fritzsche et al 2008 J. Phys. B: At. Mol. Opt. Phys. 41 165601) reveals some important differences which are discussed in terms of various ionization mechanisms and their theoretical implementations in two alternative approaches. Show more
