The production of UF/sub 6//sup -/ by reaction of a collimated stream of fluorine gas with a resistively heated uranium wire was studied at temperatures from 870 to 1020/sup 0/C and pressures less than 10/sup -3/ torr. At these temperatures below the uranium melting point, the formation of UF/sub 3/ intermediate on the uranium surface resulted in low UF/sub 6//sup -/ yields. The kinetic energy of the UF/sub 6//sup -/ ion was on the order of thermal energies. The work function of uranium was measured to be 4.20 +- 0.14 eV.
