Nucleation dynamics in neon trimer photoionization: a time-dependent modelling

Neon trimer 3D photoionization has been studied using a new quantum time- dependent model based on a wavelet expansion (WLE) of the time-dependent vibrational self-consistent field (TD-VSCF) equations. A detailed description of our approach is discussed. Dissociation probabilities, final vibrational populations of the fragment molecules, together with time snapshots of the angular distributions during fragmentation, are analysed. The role of the internal vibrational rearrangements occurring during the fragmentation process that follows the photoionization event is discussed in some detail and found to be of importance.
