The process of the present invention provides a gas steam of a mixture of UF6 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 UF5. After the gas stream has passed through the laser light excitation zone, XeF6 is fed into the process gas stream so the the xenon hexafluoride remains protected against the dissociating radiation. The XeF6 may be mixed with the same inert gas that is employed for the adiabatic cooling of the UF6. The XeF6 reaction with U-235 enriched UF5 produces a stable complex of UXeF11, 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 UF6 or U-235 enriched beta -UF5.
