Searching for Low Energy Protons Following the Beta Decay of <sup>32</sup>Ar

POSTER

Abstract

The decay of 32Ar is already one of the most thoroughly measured beta-delayed proton emitters. We have acquired additional data on this decay using the Gaseous Detector with Germanium Tagging (GADGET) at the National Superconducting Cyclotron Laboratory (NSCL). The unprecedented sensitivity to low energy protons provided by GADGET's Proton Detector enables us to set upper limits on the intensities of unobserved protons between 200 and 600 keV. The limits can be used to improve nuclear structure models and precision constraints on fundamental symmetries in the weak interaction. The current status of the data analysis will be presented.
