| Zusammenfassung | Refractive indices of several commercial liquid scintillation cocktails were measured bymeans of an automatic critical-angle dispersion refractometer in the wavelength range from 404.7 nm to 706.5 nm. The result are needed fot various applications. In particular, detailed Monte Carlo simulations of liquid scintillation counters that include the computation of optical light require these data. In addition, the refractive index is an important parameter for studies of micelle sizes by means of dynamic light scattering. In this work, the refractive indices were determined for Ultima GoldTM, Ultima GoldTM F, Ultima GoldTM LLT, Ultima GoldTM AB, Hionic FlourTM, Permafluor® E +, Mineral Oil Scintillator, Insta-Gel Plus, OptiPhase HiSafe 2, OptiPhase Hisafe 3, Ultima GoldTM XR, Insta-Gel Plus, AquaLight, MaxiLight, and Ultima GoldTM MV at 16° C, 18° C, 20° C and 22° C. The carbon dioxide absorber Carbo-Sorb® E was also analyzed. For some scintillators, various batches were compared and mixtures with water or nitromethane were studied. |
