The photoabsorption cross-section in Xe has been measured in order to deter
mine the features of the shake processes resulting from multiple electron e
xcitations as a function of photon energy. Double-electron transitions of [
1s4d], [1s4p], [1s4s], and [1s3d] have been detected. (C) 2001 Elsevier Sci
