Two-photon double ionization of helium in the region of photon energies 42-50 eV
We report the total integrated cross-section (TICS) of two-photon double
ionization of helium in the photon energy range from 42 to 50 eV. Our
computational procedure relies on a numerical solution of the time-dependent
Schr\"odinger equation on a square-integrable basis and subsequent projection
of this solution on a set of final states describing two electrons in
continuum. Close to the threshold, we reproduce results previously known from
the literature. The region 47-50 eV seems to have been previously unexplored.
Our results suggest that TICS, as a function of the photon energy, grows
monotonously in the region 42-50 eV. We also present fully resolved triple
differential cross sections for selected photon energies.Comment: 12 pages, 3 figure
