论文摘要
在目前的工作中，已经设计了一个实验，以直接测量瑞利比率为$ 405 $ nm和$ 432 $ nm的线性烷基苯苯，这是中微子实验的液体闪烁体检测器中的常见溶剂。垂直极化的瑞利比率确定为$（4.52 \ pm 0.28）\ times 10^{ - 6} $ m $^{ - 1} \ cdot $ sr $ sr $^{ - 1} $ at $ 405 $ nm和$ nm和$ nm和$ nm和$ nm和$ nm和$ nm和$ nm and $ nm and $ nm and $ nm and $ nm and $ nm和$ nm and $ nm and $ nm and $ nm and $ nm and $ nm和（3.82 \ pm 0.24）\ pm 0.24） sr $^{ - 1} $ at $ 432 $ nm，相应的瑞利散射长度为$ l_ {ray} = 22.9 \ pm 0.3（\ mathrm {stat。}）\ pm 1.7（\ mathrm {sys。}） 0.9（\ Mathrm {stat。}）\ pm 1.8（\ Mathrm {sys。}）$ m售价$ 432 $ nm。
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 $L_{Ray} = 22.9\pm 0.3(\mathrm{stat.})\pm 1.7(\mathrm{sys.})$ m at $405$ nm and $L_{Ray}= 27.0\pm 0.9(\mathrm{stat.})\pm 1.8(\mathrm{sys.})$ m at $432$ nm.
