Time resolved spectroscopy of rubidium exciplexes in helium nanodroplets with shaped femtosecond pulses — •Christian Giese1, Terence G.

Alkali-doped helium nanodroplets are peculiar complexes due to the extremely weak binding of the atoms to the droplet surface. Electronic excitation may induce desorption of the atom off the droplets or the formation of alkali-helium exciplex molecules [1,2]. In order to gain detailed insight into the formation dynamics of RbHe* exciplex molecules, Rb-doped helium droplets are studied by femtosecond pump-probe spectroscopy using shaped pulses.
