Abstract

Knowledge of the locations and lifetimes of core-excited autoionizing levels is important for understanding many physical processes as well as for its applicability to the generation of coherent extreme ultraviolet (XUV) and soft x-ray radiation. Experimental results on a new technique which allows the measurement of autoionizing times, linewidths, relative level positions, and transition oscillator strengths of core-excited levels are described, all to unprecedented accuracy.
