Abstract
Low-temperature (T greater than or equal to 180 K) oxidation of U(IV) by xenon trioxide accompanied by chemiluminescence is studied in a fro zen 0.2 M H2SO4 solution. It is shown that the peak of luminescence at 195 - 200 K is related to chemiluminescence of the excited uranyl ion (UO22+) formed in the oxidation of U(V), an intermediate product of t he interaction of U(IV) and XeO3.
