This result is relevant to proposed low-mass dark matter searches which seek to dissolve light target nuclei in the active volume of liquid-xenon time projection chambers. Low-energy helium recoils were produced by degrading <math><mi>\u03b1</mi></math> particles from <math><mrow><mmultiscripts><mrow><mi>Po</mi></mrow><mprescripts></mprescripts><none></none><mrow><mn>210</mn></mrow></mmultiscripts></mrow></math> with a gold foil situated on the cathode of a liquid xenon time-projection chamber. The resulting population of helium recoil events is well separated from electron recoils and is also offset from the expected position of xenon nuclear recoil events."
