Sd. Bosanac, CLASSICAL WAVE-PACKET STUDY OF IMPULSIVE INELASTIC-COLLISIONS, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 28(3), 1993, pp. 195-206
A new approach to the classical description of atom-molecule collision
s is investigated. It is based on the random choice of the initial con
ditions in coordinates and the momenta. Comparison with quantum analys
is is made and it is found to be very good for transitions from the gr
ound state, whilst from the excited states the classical theory gives
good results at higher collision energies.
