“…A renewal of interest in this field was invoked by the unprecedented resolution achieved at the third-generation SR sources. [6][7][8][9][10][11][12][13][14] A narrow-band excitation provides us with large benefits also for de-excitation spectroscopy, or to be more specific, resonant Auger electron spectroscopy. If the monochromator bandwidth is smaller than the lifetime width of the coreexcited state, the spectral widths of the resonant Auger emission lines are not determined by the lifetime width of the core-excited state but is determined by the convolution of the monochromator bandwidth, the bandwidth of the electron energy analyzer and the Doppler width due to thermal motion of the sample gases.…”

This article provides a review of the current status of core excitation and de-excitation spectroscopy studies of free atoms and molecules using a high-resolution soft X-ray monochromator and a highresolution electron energy analyzer, installed in the soft X-ray photochemistry beam line at SPring-8. Experimental results are discussed for 1s excitation of Ne, O 1s excitation of CO and H 2 O, and F 1s excitation of CF 4 .

“…The essence of the phenomenon is the following: the incoming photons ionize the Ne 1s electrons (ionization potential 870.17 eV (ref. 21)). The photoelectrons are ejected in two cones around the E vectors showing the p-wave cos 2 angular distribution, since the initial state is a 1s orbital with b ¼ 2.…”

Atomic Auger Doppler effects upon emission of fast photoelectrons

et al. 2014

View full text Add to dashboard Cite

Studies of photoemission processes induced by hard X-rays including production of energetic electrons have become feasible due to recent substantial improvement of instrumentation. Novel dynamical phenomena have become possible to investigate in this new regime. Here we show a significant change in Auger emission following 1s photoionization of neon, which we attribute to the recoil of the Ne ion induced by the emission of a fast photoelectron. Because of the preferential motion of the ionized Ne atoms along two opposite directions, an Auger Doppler shift is revealed, which manifests itself as a gradual broadening and doubling of the Auger spectral features. This Auger Doppler effect should be a general phenomenon in high-energy photoemission of both isolated atoms and molecules, which will have to be taken into account in studies of other recoil effects such as vibrational or rotational recoil in molecules, and may also have consequences in measurements in solids.
