Attosecond streaking of correlated two-electron transitions in helium
Renate Pazourek, Stefan Nagele, Johannes Feist +1
We present fully ab initio simulations of attosecond streaking for ionization of helium accompanied by shake-up of the second electron. This process represents a prototypical case…

Universal features in sequential and nonsequential two-photon double ionization of helium
R. Pazourek, J. Feist, S. Nagele +4
We analyze two-photon double ionization of helium in both the nonsequential and sequential regime. We show that the energy spacing between the two emitted electrons provides the ke…
