abstract: In this work, the photoionization dynamics of atomic krypton, argon dimers and
molecular nitrogen are investigated through a series of experiments with attosec-
ond time resolution. The attosecond time resolution is provided by a measure-
ment technique that uses a train of extreme-ultraviolet pulses. These experi-
ments were performed with a high-repetition rate (50 KHz, 75KHz, 150 KHz)
attosecond beamline and a 3-Dimensional Ion/electron momentum imaging de-
vice known as a Reaction Microscope (REMI). Using the high-repetition rate laser
along with the coincidence detection capabilities of the REMI, several intrigu-
ing phenomena associated with atomic and molecular photoionization have been
studied. These include the role of spin-orbit interactions in atomic photoioniza-
tion, the influence of Van der Waals forces on the photoionization of argon dimers
and finally various dissociation processes in molecular nitrogen.
