Research and development of new scintillation materials is mainly triggered by the growing needs of modern medical imaging, high energy and nuclear physics. Pure BaF2 crystals are widely applied as scintillation material because of its high density, high radiation resistance and good time resolution due to the fast component (< 1 ns) appearing in the emission bands around 220 and 195 nm. This f...

The scintillation response S of organic crystals depends on the nature and energy E of the incident iomzing particle, of residual range r. The specific fluorescence dS]dr is not in general proportional to the specific energy loss dE/dr. By considering the quenchng effect of the molecules damaged by the particle on the excitons ' produced by it, it is shown that dS/dr = ( A dE/dr)/(l + kB dE/dr)...
