| dc.description | We study two-photon double ionization of helium by short XUV pulses by numerically solving the time-dependent Schrodinger equation in full dimensionality within a finite-element discrete-variable-representation scheme. Based on the emission asymmetries in joint photoelectron angular distributions, we identify sequential and non-sequential contributions to two-photon double ionization for ultrashort pulses whose spectrum overlaps the sequential (? > 54.4 eV) and non-sequential (39.5 eV < ? < 54.4 eV) double-ionization regimes. © Published under licence by IOP Publishing Ltd. | |
