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.
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 \*
Multiply charged atomic and molecular ions are detected following laser multiphoton ionisation of UF, vapor under collision-free conditions. Most multiply charged molecular ions are thermodynamically unstable with respect to dissociation into singly charged fragment ions [l-3] \_ They are therefore
