Potential barrier effects in Cs 3d resonance photoemission of CsF

• We present and discuss the Cs 3d X-ray absorption spectra and resonant photoelectron emission spectra of CsF. The resonant photoelectron spectra excited at the Cs 3d absorption maxima, exhibit a strong resonance behavior. The different behaviour of participator and spectator channels and interference effects of the 4d partial photoionisation cross-section at the 3d resonances are discussed. The experimental evidence of the phenomenon of spin-orbit activated interchannel coupling in the 3d photoionization of Cs is presented. (C) 2004 Elsevier B.V. All rights reserved.
