Measurements of Rayleigh Ratios in Linear Alkylbenzene

Abstract

In present work an experiment has been designed to measure the Rayleigh ratio directly at $405$ nm and $432$ nm for linear alkylbenzene which is a common solvent used in liquid scintillator detectors of neutrino experiments. The perpendicularly polarized Rayleigh ratio is determined to be $(4.52\pm 0.28)\times 10^{-6}$ m${}^{-1}\cdot$ sr${}^{-1}$ at $405$ nm and $(3.82\pm 0.24)\times 10^{-6}$ m${}^{-1}\cdot$ sr${}^{-1}$ at $432$ nm, and the corresponding Rayleigh scattering length is $L_{Ray}=22.9\pm 0.3(stat.)\pm 1.7(sys.)$ m at $405$ nm and $L_{Ray}=27.0\pm 0.9(stat.)\pm 1.8(sys.)$ m at $432$ nm.
