โฆ Synopsis
We study the response of a highly excited Morse oscillator to an intense monochromatic field below resonance. The dynamics are calculated using a Fourier transform grid method. Above a threshold intensity the oscillator dissociates efficiently into a coherent asymptotic wave and a localized distribution of oscillator states. A number of features of the dissociation probability bear a strong resemblance to the microwave ionization of hydrogen.

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
