Excellent pulse height and pulse shape discrimination performance has been obtained for liquid scintillators containing as much as 10 wt.%6Li‐salicylate dissolved in a toluene‐methanol solvent system using naphthalene and 9,10 diphenylanthracene as intermediate and secondary solutes. This solution has improved performance at higher6Li‐loading than solutions in dioxane‐water solvent systems, and remains stable at temperatures as low as −10°C. Cells as large as 5 cm in diameter and 15.2 deep have been prepared which have a higher light output for slow neutron detection than10B‐loaded liquids. Neutron efficiency calculations are also presented.
