We present a versatile transportable experimental MOTRIMS setup consisting of a dark SPOT [1] for Rb atoms combined with a recoil ion momentum spectrometer (RIMS) [2]. Due to the low thermal spread of the target atoms, the recoil ion momentum can be measured with very high accuracy. We will study multiphoton ionization occuring during the interaction of the target atoms with ultrastrong laser pulses. At GSI, the same setup will be used for the investigation of correlation effects in multiple charge transfer processes in collisions between ultracold atoms and slow highly charged ions.
First experimental results, achieved at the MOTRIMS setup at the KVI Groningen, on the energy dependence of double electron transfer in collisions between laser-cooled Na and O6+ will be presented.
