Abstract :
The measurement of the scintillation efficiency for xenon nuclear recoils relative to that for 122 keV γ-rays is reported in the energy range from 5 keV to 140 keV. Prior to those measurements, the performance of the chamber with respect to the light collection efficiency, energy, time and position resolutions was assessed using 122 keV and 511 keV γ-rays.
