Abstract: (Elsevier)

Measurements have been performed with a 2.85 MeV mono-energetic neutron beam of relative scintillation efficiency and pulse-shape for nuclear and electron recoils in NaI(Tl) and CaF 2 (Eu). Scintillation efficiencies in NaI(Tl) relative to 60 keV gamma events were found to be 27.5±1.8% for Na recoils (recoil energy E rec >4 keV) and 8.6±0.7% for I recoils (E rec >10 keV). Relative scintillation efficiencies in CaF 2 (Eu) for Ca and F recoils show some evidence for a fall with energy (17% to 8% for F) for 10 keV
