摘要：

The high-frequency Floquet theory is applied to a particle bound by a Morse potential. Rates calculated in the acceleration frame with the golden rule for one- and two-photon dissociation are compared to those of an accurate multichannel resonance calculation. It is found that while the one-photon rate is correctly determined by the golden rule, the two-photon above threshold dissociation (ATD) is indirect (as in the length or velocity gauges). It is induced by a continuum-continuum interaction and is not provided by a simple application of the golden rule. (C) 1999 John Wiley & Sons, Inc.
