Abstract
The fluorescence of toulene based liquid scintillator (toulene +6 g/l butyl-PBD +0.1 g/l POPOP) has been studied as a function of temperature in the range 220 to 290 K. It has been observed that under gamma excitation the light output increases with decrease in temperature by a factor of 1.43. The data are well encompassed by an Arrhenius relation, in which the activation energy of rate process (0.21 eV) is compatible with thermally-activated diffusion mechanism.
