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 CaF2(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 Erec > 4 keV) and 8.6 ± 0.7 % for I recoils (Erec > 10 keV). Relative scintilla...
