Abstract
  • We present Auger spectroscopy studies of large krypton clusters excited by soft x-ray photons with energies on and just above the 3d(5/2) ionization threshold. The deexcitation spectra contain new features as compared to the spectra measured both below and far above threshold. Possible origins of these extra features, which stay at constant kinetic energies, are discussed: (1) normal Auger process with a postcollision interaction induced energy shift, (2) recapture of photoelectrons into high Rydberg orbitals after Auger decay, and (3) excitation into the conduction band (or 'internal' ionization) followed by Auger decay. The first two schemes are ruled out, hence internal ionization remains the most probable explanation. (C) 2007 American Institute of Physics. (literal)
