“…As a consequence, the energy resolution of the light was not a limiting factor for the measurements. The photon energy was calibrated using literature values of the Kr 3d near-edge x-ray absorption spectrum [30], while the time-to-energy conversion was calibrated using known values of Xe and Kr Auger lines [31,32], augmented for low electron energies by the 2 D photoelectron lines of Kr corrected for the PCI shift associated with single Auger decay.…”

Influence of double Auger decay on low-energy 3d photoelectrons of krypton.Physical Review A. Atomic, Molecular, and Optical Physics, 86(2) Effects of postcollision interaction (PCI) observable in low-energy 3d photoelectron spectra of Kr, which are associated with double Auger decay of the created inner-shell vacancy, are investigated by a combined experimental and theoretical approach. Measurements are based on an efficient multielectron coincidence method. Calculations have been carried out in the framework of a semiclassical approach. Our investigation reveals strong PCI distortion of the photoelectron line shapes, which depends on the kinematics of the process and the characteristics of the double Auger decay.

“…As a consequence, the energy resolution of the light was about 20 meV and hence not a limiting factor for the measurements. The monochromator was calibrated using literature values of the Kr 3d near-edge x-ray absorption spectrum [14] while the time-to-energy conversion was calibrated using known energies of Xe and Kr Auger lines [15].…”

Citation for the original published paper (version of record):Andersson, E., Fritzsche, S., Linusson, P., Hedin, L., Eland, J H. et al. (2010) Multielectron coincidence study of the double Auger decay of 3d-ionized krypton.Physical Review A. Atomic, Molecular, and Optical Physics, 82(4) Multielectron coincidence data for triple ionization of krypton have been recorded above the 3d ionization threshold at two photon energies (140 and 150 eV). Three principal transition pathways have been observed, two involving double Auger transitions from Kr + , and one involving single Auger transitions from Kr 2+ created by direct single-photon double ionization. The decay of the 3d 9 2 D 5/2,3/2 states in Kr + has been analyzed in some detail and is found to be strongly dominated by cascade processes where two electrons with well-defined energies are emitted. The decay paths leading to the 4s 2 4p 3 4 S, 2 D, and 2 P states of Kr 3+ are analyzed and energies of seven intermediate states in Kr 2+ are given. A preliminary investigation of the decay paths from Kr + 3d 9 4p 5 nl shake-up states has also been carried out.

“…Random coincident background events are subtracted using standard statistical methods. The detection energies of the hemispherical electron energy analyzers have been calibrated using the L 2,3 M 2,3 M 2,3 Auger spectrum of argon, 27 while the angular calibration of the analyzers has been determined using the well-defined minimum in the differential cross section for elastic scattering of 60 eV electrons from argon. 28 In dynamical TDCS measurements, the scattered electron is detected at a fixed forward scattering angle (θ a ) with respect to the incident electron beam direction, while ejected electron angular distributions are measured by scanning the ejected electron energy analyzer and detecting electrons at a number of different ejected electron angles (θ b ) within the scattering plane.…”

Cross section data for electron scattering from DNA are important for modelling radiation damage in biological systems. Triply differential cross sections for the electron impact ionization of the highest occupied outer valence orbital of tetrahydrofurfuryl alcohol, which can be considered as an analogue to the deoxyribose backbone molecule in DNA, have been measured using the (e,2e) technique. The measurements have been performed with coplanar asymmetric kinematics at an incident electron energy of 250 eV, an ejected electron energy of 20 eV, and at scattered electron angles of −5 • , −10 • , and −15 • . Experimental results are compared with corresponding theoretical calculations performed using the molecular 3-body distorted wave model. Some important differences are observed between the experiment and calculations.
