Electron shakeoff following the ?+ decay of trapped 35Ar+ ions

Abstract

The electron shakeoff of $^{35}$Cl atoms resulting from the $β$$^+$ decay of $^{35}$Ar$^+$ ions has been investigated using a Paul trap coupled to a recoil-ion spectrometer. The charge-state distribution of the recoiling daughter nuclei is compared to theoretical calculations accounting for shakeoff and Auger processes. The calculations are in excellent agreement with the experimental results and enable to identify the ionization reaction routes leading to the formation of all charge states.
