The production of uranium vapors has been studied in the /sup 5/L/sup 0//sub 6/ ground state using a pulsed hollow cathode lamp. The evolution of the /sup 238/U (/sup 5/L/sup 0//sub 6/) concentration with time has been studied with Xe and Ar as buffer gases. A density of 2.7 x 10/sup 13/ atoms cm/sup -3/ was obtained with Xe as a buffer gas. In addition, those measurements, obtained from the absorption of a laser beam tuned to the 5758.143 A (/sup 5/L/sup 0//sub 6/-17,361/sup 7/L/sub 6/) transition, allowed the determination of the transition probability A=2.1 x 10/sup 5/ sec/sup -1/ and of the branching ratio BR=0.08 for this transition.
