The vibrational excitation of a diatomic Morse-oscillator by collinear collision with a third atom is treated in the quantum-mechanical impulse approximation. A closed analytic expression for the transition probabilities Pn'n is derived. It is discussed, how the Pn'n will change as a function of the

The dynamic description of a collision in a medium is reformulated using an interaction picture. This transformation can be used both as a computational device and as a basis for analytical approximations. Numerical results for the problem of a collinear atom-oscillator collision including friction
