Kinematically complete ion-atom collision experiments: Ionization of atomsin strong fields

When fast highly charged ions pass a target atom or molecule at distances o f a few atomic units electric fields of up to 10(11)V/cm are acting on the target electrons. Depending on the field strength one or several electrons are released from the target atom by these super-strong electric pulses wit hin the collision time of typically 10(-18) s. In a series of kinematically complete experiments the dynamics of the ionization process has been studi ed for single up to triple ionization of atoms. In these experiments the co mplete many-particle final state in momentum space has been mapped with hig h resolution.
