Abstract: The beta decay process offers unique possibilities to search for so-called exotic, non-standard model components in the weak interaction, and for testing its fundamental symmetries. Sensitive candidates for such studies are nuclei at or close to the N = Z line for which nuclear structure-related corrections are well under control. We present here an overview of the current status of this field and discuss prospects for further significant progress in the forthcoming years.

TL;DR: In this paper, the authors focus on the accuracy of the description of the electron processes in the energy range between 100 and 1000 keV and investigate the effect of different simulation parameters and multiple scattering models on the backscattering coefficients.
Abstract: Geant4 simulations play a crucial role in the analysis and interpretation of experiments providing low energy precision tests of the Standard Model. This paper focuses on the accuracy of the description of the electron processes in the energy range between 100 and 1000 keV. The effect of the different simulation parameters and multiple scattering models on the backscattering coefficients is investigated. Simulations of the response of HPGe and passivated implanted planar Si detectors to β particles are compared to experimental results. An overall good agreement is found between Geant4 simulations and experimental data.

TL;DR: In this article, a Paul trap coupled to a recoil-ion spectrometer was used to investigate the electron shakeoff of $ ∆$Cl atoms resulting from the decay of ions.
Abstract: The electron shakeoff of $^{35}$Cl atoms resulting from the $\beta$$^+$ 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
