Decay dynamics of transient molecular ions

The basic understanding of decay dynamics of poly-atomic molecules is a topic of current and fundamental interest. Momentum resolved study of fragmentation of simple molecules unravels the breakup dynamics of the transient, often multiply charged, molecular ions formed in the collision reactions. These molecular ions decay into the atomic ions via different routes, namely, concerted and sequential breakup processes, giving rise to fragment ions with definite momentum correlations. These are clearly identified by analysing the momentum correlations in the Newton diagrams and by looking at the energy partition in the 3-body Dalitz plots. I will discuss the decay dynamics of two tri-atomic systems, namely, CO2 and N2O in collisions with fast electrons and highly charged heavy ions [1]
