要旨:
In this work the dynamics of one- and two-electron transitions in ion-lithium collisions
is investigated. The measurements are performed with a novel experimental
technique (MOTReMi) combining a magneto-optically trapped (MOT) Li target
with a Reaction Microscope (ReMi) enabling the momentum resolved and coincident
detection of the target fragments. This apparatus was implemented in the
ion storage ring TSR providing electron-cooled projectile beams with high currents
and low momentum spread. Due to the high resolution and by means of optical
excitation, for the first time initial state selective fully differential cross sections for
ion-impact induced ionization and charge transfer became available. Transitions of
1s, 2s and 2p target electrons were investigated shedding light on the role of the projectile coherence length, electronic correlation in two-electron transitions and target polarization effects, thereby enhancing our understanding of the few-body problem in quantum dynamics.
