On the role of shake-off in single-photon double ionization
T. Pattard, T. Schneider, J. M. Rost
The role of shake-off for double ionization of atoms by a single photon with finite energy has become the subject of debate. In this letter, we attempt to clarify the meaning of sh…
Quasiclassical double photoionization from the 2^{1,3}S excited states of helium including shakeoff
A. Emmanouilidou, T. Schneider, J. -M. Rost
We account for the different symmetries of the 2^{1,3}S helium excited states in a quasiclassical description of the knockout mechanism augmented by a quantum shakeoff contribution…
Separation and identification of dominant mechanisms in double photoionization
Tobias Schneider, Peter Leszek Chocian, Jan-Michael Rost
Double photoionization by a single photon is often discussed in terms of two contributing mechanisms, {\it knock-out} (two-step-one) and {\it shake-off} with the latter being a pur…
Intermanifold similarities in partial photoionization cross sections of helium
Tobias Schneider, Chien-Nan Liu, Jan-Michael Rost
Using the eigenchannel R-matrix method we calculate partial photoionization cross sections from the ground state of the helium atom for incident photon energies up to the N=9 manif…
