✦ Synopsis

The Heisenberg and Liouville dynamical equations are mapped using the Wave-Packet Phase Space Representation.

A semiclassical perturbative expansion is introduced -the Quasi-Causal Approximation -for the Green function and an expression for transition probabilities is derived up to the first order.

The accuracy of the Wigner propagation method is studied for stationary as well as non-stationary states of Morse oscillators. We investigate the possibility of improving the approach by introducing an effective potential. We find that the Wigner propagation method is accurate only for the ground st
