A new glass ceramic composed of a lithium borate glass matrix containing Eu-doped BaCl 2 crystals has been developed for thermal neutron radiography, and has been tested for sensitivity to γ-radiation. It is shown to exhibit photostimulated luminesc

We present a simple method for measuring the neutron flux from an 241Am-Be radioactive source. The yield determination is based on counting (n,p) + (n,d) and (n,α) events in a NaI(Tl) scintillator. This technique offers the advantages of two indepen

The 6Li(n, α)3H cross section has been precisely measured between 12.0 and 18.2 MeV. The reactions are observed in a 6LiI(Eu) scintillator which serves simultaneously both as a target and a detector of the charged particle reaction products. A caref
