First observation of the ground-state electron-capture of $^{40}$K Potassium-40 is a naturally-occurring isotope whose radioactivity impacts estimated geological ages spanning billions of years, nuclear structure theory, and subatomic rare-event searches -- including those for dark matter and neutrinoless double-beta decay. The decays of this long-lived isotope mus...

Recent paper on pyrene as a wavelength shifter:

Development and characterization of a slow wavelength shifting coating for background rejection in liquid argon detectors We describe a technique, applicable to liquid-argon-based dark matter detectors, allowing for discrimination of alpha-decays in detector regions with …
