Abstract
The Kr M4,5-NN Auger transitions are studied in the kinetic energy region 24 - 59 eV by using non-monochromatic electron beam and a high resolution electrostatic analyzer. Among the sixty four features observed, fifty five are assigned, while nine stay unassigned. The post-collision interaction (PCI) effects in the M5-N1N1(1S0) and M5-N2,3N2,3(1S0) Auger peaks are studied as a function of electron incident energy approaching the M5 edge (95.04 eV). The PCI shifts are found to be well represented by an exponential function of the excess energy with exponents β = (-0.99±0.05 and -3.08±0.05) for the N2,3N2,3(1S0) and N1N1(1S0) peaks, respectively. The M2,3-M4,5N Coster-Kronig transitions are studied in kinetic energy region 65 - 110 eV and at incident energies from 120 to 2019 eV. Owing to a high resolution twelve well resolved satellites in the region bellow 90 eV are observed, while in the region 90 - 110 eV two broad features are assigned to the M2,3-M4,5N2,3 C-K peaks with intensity ratio (M3/M2 = 2.37) are observed. Comparison is made with available data from literature.
