โœฆ Synopsis

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 atomic molecules are presented.

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
