Abstract
The process of the present invention provides a gas steam of a mixture of UF.sub.6 isotopes and an inert gas, e.g. nitrogen, which is adiabatically expanded through a nozzle into a laser light excitation zone and photodissociated to form U-235 enriched UF.sub.5. After the gas stream has passed through the laser light excitation zone, XeF.sub.6 is fed into the process gas stream so the the xenon hexafluoride remains protected against the dissociating radiation. The XeF.sub.6 may be mixed with the same inert gas that is employed for the adiabatic cooling of the UF.sub.6. The XeF.sub.6 reaction with U-235 enriched UF.sub.5 produces a stable complex of UXeF.sub.11, which polymerizes to poly(pentafluoroxenonium(+1)-hexafluorouranate V), an intermediate product of the present process. The intermediate product may be thermally decomposed to form U-235 enriched UF.sub.6 or U-235 enriched .beta.-UF.sub.5.
