Energy and charge transfer processes in helium nanodroplets — •Marcel Mudrich — Department of Physics and Astronomy, Aarhus University, Denmark

Currently the focus is shifting towards ICD and related interatomic decay processes occurring in more complex media such as biomolecules and condensed phase systems. In this respect, pure and doped helium nanodroplets offer interesting perspectives: They have a homogenous, superfluid density, and they are able to embed, aggregate, and cool atoms and molecules, while their constituents are simple two-electron atoms. Thus helium droplets are ideal for tailoring all kinds of unsupported hetero-complexes.

I will report on our recent experiments probing ICD, ETMD, and related correlated decay processes in pure and doped helium nanodroplets initialed by cw or pulsed EUV radiation. In particular, we find that multiple ionization of embedded species can be either facilitated or hampered by the surrounding helium nanodroplets.
