Beta-delayed gamma decay of <sup>32</sup>Ar

POSTER

Abstract

Positron decay of 32Ar can be used to precisely study nuclear structure and search for physics beyond the Standard Model. Data from positron decay of 32Ar was collected at the National Superconducting Cyclotron Laboratory (NSCL) using the Gaseous Detector with Germanium Tagging (GADGET) system. GADGET detects both gamma and proton emissions from radioactive nuclides. This study’s goal is to analyze the gamma rays emitted following positron decay of 32Ar. The 32Ar was acquired serendipitously during an experiment that was focused on the decay of 31Cl. The high-resolution of the germanium detectors within GADGET allows us to gain a better understanding of the decay scheme of 32Ar in addition to searching for any coincidences between proton and gamma decays.
