Use of Li6I(Eu) as a Fast-Neutron Detector and Spectrometer

A review is given of experiments carried out in an investigation of the scintillation response of Li6I(Eu) to fast neutrons. A considerable improvement in fast-neutron resolution is realized by operation of the crystal at low temperatures. Pulse-height spectra have been recorded for neutrons from various sources providing both line spectra and continuous spectra. These experiments indicate possible applications of Li6I(EU) as a fast-neutron detector and spectrometer.
