The valence photoelectron satellite spectra of Kr and Xe

Photoelectron spectra of Kr and Xe were measured with high resolution in the region of ns2np4n?l (n=4 for Kr, n=5 for Xe) states. Experimental results are compared with optical data, with previous photoelectron studies and with configuration interaction calculations. A number of previously unobserved photoelectron satellites were detected. Some new assignments for the photoelectron satellite lines, particularly for Kr, are suggested.
