Fig. 1: Total quanta (photons and electrons) released from various recoils in LXe.
From: HydroX, a light dark matter search with hydrogen-doped liquid xenon time projection chambers
The blue curve shows the quanta for low energy Xe recoils in LXe as modeled by NEST. The magenta line shows a SRIM calculation35 for H recoils, assuming only electronic stopping contributes, with about 5× more quanta produced per unit energy relative to Xe. The green and dashed black lines show two independent predictions for yields from He recoils in LXe, one from SRIM package and the second from NEST. The two models for helium are in good agreement.
