We report the vacuum-ultraviolet absorption spectrum of doubly ionized rubidium observed in a dual laser plasma experiment. The spectrum exhibits discrete structure due to 3d-nl excitations superimposed on the underlying 4s and 4p continua. The total photoionization cross section, computed within the framework of Fano theory, shows very good agreement with experiment.
