The optogalvanic effect of doubly ionized uranium produced in a hollow-cathode discharge is studied by using various rare gases and their mixtures as fill gases. In general, the pressures at which the optogalvanic signal is optimized are higher than those that optimize the emission intensities, and, under equivalent experimental conditions, the enhancement of the optogalvanic signal is more than 1 order of magnitude greater than the enhancement of the emission intensity. When a single rare gas is used, the optogalvanic signal is found to increase when the ionization potential of the rare gas increases. The signals in Ne are 1 order of magnitude stronger than the signals in Xe. When a He--Xe mixture containing 1% Xe is used, signals are obtained that are, on the average, 30 times stronger than those in Ne. This enhancement behavior can be used as a signature of U III transitions.
