Stochastic dissociation of diatomic molecules [PDF]

The Journal of Chemical Physics, 2005
The fragmentation of diatomic molecules under a stochastic force is investigated both classically and quantum mechanically, focusing on their dissociation probabilities. It is found that the quantum system is more robust than the classical one in the limit of a large number of kicks. The opposite behavior emerges for a small number of kicks.
