Abstract: We investigate the possibility to monitor the dynamics of autoionizing statesin real time and control the yields of different ionization channels in heliumby simulating XUV-pump IR-probe experiments focused on the N=2 threshold. TheXUV pulse creates a coherent superposition of doubly excited states which isfound to decay by ejecting electrons in bursts. Prominent interference fringesin the photoelectron angular distribution of the $2s$ and $2p$ ionizationchannels are observed, along with sizable out-of-phase quantum beats in theyields of the corresponding parent ions.
