The KDK (potassium decay) experiment

Abstract

Potassium-40 (40{}^{40}K) is a background in many rare-event searches and may well play a role in interpreting results from the DAMA dark-matter search. The electron-capture decay of 40{}^{40}K to the ground state of 40{}^{40}Ar has never been measured and contributes an unknown amount of background. The KDK (potassium decay) collaboration will measure this branching ratio using a 40{}^{40}K source, an X-ray detector, and the Modular Total Absorption Spectrometer at Oak Ridge National Laboratory.
