Fast neutron and alpha detection using LiBaF/sub 3/ scintillator

Pulse-shape discrimination techniques using the scintillator LiBaF/sub 3/ allow very clean separation of densely ionizing radiation (protons, tritons, alphas, etc.) from less densely ionizing radiation (electrons). The pulse-shape discrimination is based on the presence or absence of subnanosecond core-valence luminescence and in crystals doped with Ce/sup +3/ the presence or absence of Ce lumines...
