Description:
Author(s): R. Pazourek, J. Feist, S. Nagele, E. Persson, B. I. Schneider, L. A. Collins, and J. Burgdörfer We analyze two-photon double ionization of helium in both the nonsequential ( ℏ ω 〈 I 2 ≈54.4 eV ) and sequential ( ℏ ω 〉 I 2 ) regime. We show that the energy spacing Δ E = E 1 - E 2 between the two emitted electrons provides the key parameter that controls both the energy and the angular distribution and reveal... [Phys. Rev.
