Abstract

The temporal behavior of uranium neutrals in the postdischarge conditions in a pulsed hollow cathode discharge has been investigated by monitoring the time dependent absorption of the output radiation of a single-axial-mode dye laser by uranium atoms. Studies of the kinetics of the absorption suggest that electron ion recombination followed by deactivation, Penning ionization, and diffusion to the cathode wall are the dominant mechanisms in the postdischarge conditions.
