A neodymium-loaded liquid scintillator

One promising approach to the search for neutrinoless double beta (0ν2β) decay is the use of liquid scintillators with double β-decay sources dissolved in them. The ¹⁵⁰Nd isotope is the one best suited to observing this process. Samples of liquid scintillators based on linear alkylbenzene with a neodymium mass fraction of 0.32% are described in this work; neodymium 4-methyloctanoate was used as a Nd-loaded additive. The spectral-luminescent and scintillation properties of the new materials were studied. The possibility of using the obtained compounds in experiments to search for 0ν2β decay is demonstrated.
