Calculation of Electron Shake-Off for Elements fromZ=2to 92 with the Use of Self-Consistent-Field Wave Functions

Electron shakeoff following theβ+decay ofNe+19andAr+Fabian1, Fléchard2, Pons3 et al. 2018Phys. Rev. A14160View full textAdd to dashboardCite

“…The charge-state distributions of the recoiling daughter nuclei were compared to theoretical calculations based on the sudden approximation and accounting for subsequent Auger processes. The excellent agreement obtained for 35 Cl is not reproduced in 19 F. The shortcoming is attributed to the inaccuracy of the Independent Particle Model employed to calculate the primary shakeoff probabilities in systems with rather low atomic numbers. This calls for more elaborate calculations, including explicitly the electron-electron correlations.…”

“…For multi-electron systems with more than two electrons, experimental results obtained in the β − decay of a collection of radioactive rare gas [18] have been compared to self-consistent-field calculations [19] to test theoretical predictions for electron SO from the inner shell and from the outermost shell. This work, however, did not allow a precise test of the theory since it did not discuss the complete charge distribution and did not include the Auger emission subsequent to the primary SO ionization.…”

“…The electron shakeoff of 19 F and 35 Cl atoms resulting from the β + decay of 19 Ne + and 35 Ar + ions has been investigated using a Paul trap coupled to a time of flight recoil-ion spectrometer. The charge-state distributions of the recoiling daughter nuclei were compared to theoretical calculations based on the sudden approximation and accounting for subsequent Auger processes.…”

In-trap conversion electron spectroscopy

“…From the ratios of the intensities of the conversion electron lines and the low-energy background one can estimated the probability for the creation of a vacancy as 15 %. This value is of the same order of magnitude as the typical probability of electron shake-off as a consequence of β-decay [23].…”

Multiple-electron excitation in X-ray absorption: a screened model of the core-hole–photoelectron potential

“…The solid line shows the result calculated using equation (13). The points are experimental data: diamonds from , crosses from Samson et al (1992), open squares with error bars from Holland et al (1979), crosses with error bars from Wight & Van der Viel (1976) and triangles with error bars from Carlson et al (1968).…”
