The Kr valence photoelectron satellite lines in the photon energy region below the 3d threshold

The photoelectron spectrum of krypton was recorded with various photon energies from 60 to 88 eV in the binding energy range of Kr 4s photoelectron line and valence satellite lines. Strong photon energy dependence was found in the experimental cross-sections of the satellite lines. The high experime...

Description
Summary:The photoelectron spectrum of krypton was recorded with various photon energies from 60 to 88 eV in the binding energy range of Kr 4s photoelectron line and valence satellite lines. Strong photon energy dependence was found in the experimental cross-sections of the satellite lines. The high experimental resolution of the measured spectra allowed us to really separate close lying states. This, together with the measurement of the angular anisotropy parameter beta at hnu = 88 eV enabled us to verify the origin of the satellite lines, i.e. whether they are created by shake-up, conjugated shake-up, or by correlation of bound or continuum states during 4s or 4p photoionization.
