摘要

以Nd(III) 3,5,5-三甲基己酸酯为基础，添加溶剂TBP，建立了用于双中微子\(\beta\)衰变测定的液体有机闪烁体。红外光谱表明TBP与羧酸钕形成额外的配位键，从而阻止其水解和聚合。研究表明，紫外分光光度法是研究闪烁体纯度和稳定性的最佳方法。闪烁体组成[LAB \(+\) BPO (3g /L) \(+\) TBP (6.3 \(\%\)) \(+\) Nd (\(5.9\pm 0.2\) g/L)]相对于闪烁体[LAB \(+\) BPO (3g /L)]的产光率为78 \(\%\)。

Optimization of the Composition of Nd-Containing Scintillator to Increase Its Light Yield and Stability

Based on Nd(III) 3,5,5-trimethylhexanoate and an additional solvent TBP, the composition of a liquid organic scintillator for the determination of double neutrinoless \(\beta\) decay was developed in LAB. IR spectroscopy has shown that TBP forms additional coordination bonds with neodymium carboxylate and thereby prevents its hydrolysis and polymerization. It has been shown that the optimal method for studying the purity and stability of a scintillator is UV spectrophotometry. The light yield of the scintillator composition [LAB \(+\) BPO (3 g/L) \(+\) TBP (6.3\(\%\)) \(+\) Nd (\(5.9\pm 0.2\) g/L)] is 78\(\%\) relative to the scintillator [LAB \(+\) BPO (3 g/L)].

期刊介绍： Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
