UFs undergoes decomposition m the presence of SF6 when mixtures of both are madiated wrth a TEA CO2 laser. The mechanism for UFe decomposition may involve vrbrational energy transfer from excited SF, and laser absorption from the same laser pulse by excited UFe in its vibrational quasi-continuum \*

Multiphoton ionization of UF s as a probe of laser-induced dissociation of UF 6 is investigated using an ionization chamber. Results are given on the fluence dependence of the multiphoton ionization process and on the pressure dependence of the UF 6 photodissociation.
## Infrared multiphoton dissociation experiments in difluorochloromethane have been carried out m the presence of different proportions of nitrogen and argon. The influence of homogeneous and heterogeneous collisions in the process is studied and discussed in terms of an intense bottleneck effect
Crossed laser and molecular beams were. used to obtain the recoii-energy distributions of fragments in the study af multiphoton dissociation of SF& The measured recoil-ener\_gy distributions of SFs under a laser excitation of = 10 J/cm' are in good agreement with the theoretical prediction of the RR
