In studies of the ionization dynamics in atoms and molecules after light-matter interaction, usually electrons and/or ions are detected, as they are the natural products of the ionization process. Investigating ionization dynamics in molecular hydrogen is therefore predominantly done by measuring charged particles . Here, we experimentally consider the complementary approach of attosecond transient-absorption spectroscopy (ATAS) and aim at the energy region around the Qn doubly excited resonances. First results of this technically challenging experiment will be presented, with emphasis on a systematic study of various obstacles that arise when searching for weak and broadband spectral signatures in an ATAS experiment.
