A Numerical Study of the Mean Trajectory Approximation in a Non-Adiabatic Process.
Abstract
We present numerical results obtained with the mean trajectory approximation applied to a non-adiabatic process described by a curve crossing model. We compare them to the results given by the customary trajectory approximation which uses one adiabatic potential to generate the nuclear motion, and to the results given by Nikitin's formula. We find that at low kinetic energy the three procedures give very different results. The differences are caused by the fact that the mean trajectory method includes quantum effect in the effective potential used for the classical motion. We also discover an unexpected behavior: under certain conditions the transition probability seems to become a random function of the incident energy. (Author)
