The synchrotron-radiation-induced electron emission spectra from evapo
rated KF films have been measured by varying the photon energy across
the K 2p ionization threshold. The excitation of the K 2p electrons to
the pre-edge resonances creates resonant Auger spectra which are char
acterized by essentially sharper line shapes and by energy shifts of 7
eV to higher kinetic energies as compared with the normal Auger spect
ra.
