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.
