Abstract

Following a brief discussion of uranium isotope separation using lasers, the delayed coincidence method of measuring atomic mean lives with pulsed electron beams utilized here is described along with the beam source used to supply the free uranium atoms for measurement. Experimental details involved in the lifetime measurement are next discussed followed by the effect of resonance radiation imprisonment on the measured lifetimes. Finally, lifetime measurements involving the 3584.9 Å and 5915.4 Å transitions in natural uranium are described, and the previously reported result of 7.3 ± 1.1 ns ior the mean life of the upper level of the 3584.9 Å transition (27886.99 cm -1 ) is presented.
