We present a theoretical description of the dynamics of vibrational wave packets in the 1 gstate of Xe 2 . As an illustration, a simulation of a picosecond pump excitation-probeionization laser experiment is carried out. The initial wavepacket is calculated using anexplicit modelling of the short-pulse excitation process and propagated for up to160 picoseconds. Evidence of fractional and full revivals of the wavepacket has beenfound and analyzed. The time delayed ionization signal is simulated using first orderperturbation theory and shows clear oscillations corresponding to the temporaldevelopment of the wavepacket.
