TL;DR: In this paper, the relative scintillation efficiency for nuclear recoils is 0.22±0.01 in the recoil energy range 40 −70 −kV in liquid xenon scintillator detectors.
Journal ArticleDOI
Detailed calculation of test-mass charging in the LISA mission
TL;DR: In this paper, the authors report on detailed charging simulations with the Geant4 toolkit, using comprehensive geometry and physics models, for Galactic cosmic-ray protons and helium nuclei.
