The present work demonstrates that the number of scattering problems which can be handled accurately by the semiclassical (thawed) Gaussian method can be increased substantially if the calculations are done within the framework of the interaction picture. Examples for photodissociation of three atom
The semiclassical Gaussian wave packet method is formulated in the classical interaction picture. Since the intrraclionpicture classical trajectories that govern the packet dynamics are slowlg 'wing in time, the approximare remporal propagation of the wavefunction is more accurate. Two numerical exa
Generalization of Gaussian trial wave functions in quantum molecular dynamics models is introduced, which allows for long-range correlations characteristic for composite nuclear fragments. We demonstrate a significant improvement in the description of light fragments with correlations. Utilizing eit
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.
