Electron shakeoff following the β+ decay of 19Ne+ and 35Ar+ trapped ions

Journal Contribution - Journal Article

© 2018 American Physical Society. The electron shakeoff of F19 and Cl35 atoms resulting from the β+ decay of Ne+19 and Ar+35 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. The excellent agreement obtained for Cl35 is not reproduced in F19. 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.
