Inelastic collisions which give rise to rotational energy transfer (RET) at several different relative energies are examined for He and Ar projectiles interacting with Nz. Calculations are carried out within the infinite order sudden approximation (IOSA) for the dynamics and repeated more accurately
The time-dependent self-consistent field (TDSCF) approximation is applied to the coupled-mode vibrational dynamics of highly anharmonic quantum clusters, and its validity and accuracy for such systems are tested against exact quantum calculations. The calculations are pursued for bound but non-stati
Gaussian wavepackets in phase space, which are constructed to have the exact first and second moments with respect to the coordinates and momenta, are used to develop self-consistent equations of motion for the semiclassical time evolution of interacting anharmonic systems. The equations apply to pu
