Impact of Interatomic Electronic Decay Processes on Xe 4d Hole Decay in the Xenon Fluorides

, 2004
A hole in a 4d orbital of atomic xenon relaxes through Auger decay after a lifetime of 3 fs. Adding electronegative fluorine ligands to form xenon fluoride molecules, results in withdrawal of valence-electron density from Xe.
