✦ Synopsis

An approlimatc approach is dcvelopcd to study the interfcrcncc of one-and twoquantum processes in collinear collisions of an atom and a harmonic oscillator. !n deriving an esplicit espression for vibrational transition probabilities, oncquantum processes arc trcatcd rigorously. while the contributions of two-quantum proccsscs are solved in first order. The intcrfcrcnce is found IO bc strong in fhe collision systelns such as Hz + lb. cspecinlly ui high collision energies. In the collisions of a light atom with a heavy diatom. the interference is found to bc not important even at such high cncrgics

A study of the vibration-translation energy transfer in atom-diatom collinear collisions is made. Using an algebraic approach developed by Gazdy and Micha, the time evolution operator of the linearly driven parametric oscillator (LDPO) is obtained, and used to transform the cubic part of the interac
