Complete reconstruction of bound and unbound electronic wavefunctions in two-photon double ionization
To be complete, the characterization of the photoionization process of atoms and molecules requires the extraction of all quantum-mechanical phases and amplitudes. So far, complete experiments have accessed on...

Two-step excitation of Rb atoms on He nanodroplets
We present the first sequential laser excitation of atom-doped helium nanodroplets. Rubidium atoms on the surface of helium nanodroplets are selectively excited with a continuous wave laser to the 52P1/2 state s...

Spectroscopy of alkali atoms (Li, Na, K) attached to large helium clusters
Large liquid helium clusters (Hen, n ≈ 104) produced in a supersonic jet are doped with alkali atoms (Li, Na, K) and characterized by means of laser induced fluorescence. Each cluster contains, on average, less t...
