Abstract
We present the results of a test done with a Liquid Xenon (LXe) detector fo r "Dark Matter" search, exposed to a neutron beam to produce nuclear recoil events simulating those which would be generated by WIMP's elastic scatter ing. The aim of the experiment was to measure directly the scintillation ef ficiency of nuclear recoil. The nuclear recoil considered in the test was i n the tens of keV range. The ratio of measured visible energy over the true recoil energy was evaluated to be about 20%, in good agreement with the th eoretical predictions. (C) 2000 Elsevier Science B.V. All rights reserved.
