Photoelectron spectra of Kr and Xe were measured with high resolution in th
e region of ns(2)np(4)n'l (n=4 for Kr, n=5 for Xe) states. Experimental res
ults are compared with optical data, with previous photoelectron studies an
d with configuration interaction calculations. a number of previously unobs
erved photoelectron satellites were detected. Some new assignments for the
photoelectron satellite lines, particularly for Kr, are suggested. (C) 2001
