Abstract:

Experimental studies of associative ionization reactions involving uranium and other metal atoms in collisions with O, O2 and other atmospheric species are described. The first experiments determined the ratio of cross sections for the U O and the U O2 reactions. The second determined the absolute cross section for the U O2 to UO2 e process. Crossed beam experiments in which a metal atom beam containing both U and a second metal atom Ti, Gd, Zr, Th, Ba was crossed by a beam of either O2 or O were performed to determine the associative ionization cross sections for Ti O, Zr O, Gd O, Th O and Th O2. Crossing a U atom beam with a gas beam containing O2 and N2O yielded an absolute cross section for U N2O to UO N2. Other associative ionization processes were observed, among which were U NO to UNO e and Ba OH to Ba OH e.
