Abstract

The wide bandwidth single color multiphoton ionization spectrum of uranium was measured in the spectral range of Rhodamine 6G dye, using the fast ( iO sec.) pulsed optogalvanic effect generated by photoionization in the dark space ofa hollowcathode discharge (HCD). Results indicate that for this spectral range (between 570and 610 nm) the optogalvanic multiphoton ionization spectrum is very rich. A list of the 74 most significant photoionic lines is presented. With the help of published levels and using three resonant or quasi-resonant photons ionization schemes, proposed assignments of these lines are also presented. The line at 591,54 nm is a special case which is discussed in more detail.
