Partial Decay Rates in Driven One Dimensional HeliumCelsus Bouri1,2, Felix Jörder1, Pierre Lugan1, Vera Neimanns1, Sören Roerden1, •Klaus Zimmermann1, and Andreas Buchleitner11Albert-Ludwigs University of Freiburg — 2University of Douala, Cameroon

The continous part of the spectrum of one dimensional driven Helium below the double ionization threshold is structured by resonances, that play a vital role in its decay.

We employ the method of complex dilation to resolve the decay from a given initial state into channels, distinguishing between single and double ionization. By means of Floquet theory we tell processes with different numbers of photons involved apart.
