Query: Improved Measurements of the \b{eta}-Decay Response of Liquid Xenon with
  the LUX Detector   We report results from an extensive set of measurements of the \b{eta}-decay
response in liquid xenon.These measurements are derived from high-statistics
calibration data from injected sources of both $^{3}$H and $^{14}$C in the LUX
detector. The mean light-to-charge ratio is reported for 13 electric field
values ranging from 43 to 491 V/cm, and for energies ranging from 1.5 to 145
keV.
