This report includes information about activities in the Ames Laboratory Nuclear Safeguards and Security Program during the period 1/1/91 to 3/31/91. The first section contains a summary of research activities, the second section contains preprints of papers submitted for publication in this period, and the last section contains a discussion of administrative matters pertaining to the program. Efforts to improve the detection limits and reliability of the Inductively Coupled Plasma -- Laser Excited Atomic Fluorescence Spectroscopy (ICP-LEAFS) analysis of uranium have centered on the evaluation of excitation and emission wavelengths. Due to the broadening of the linewidth that occurs during frequency doubling, efforts were made to find a suitable transition in the fundamental region of the laser dye.
