Abstract

The ¹⁴C/¹²C ratio in 4.8 m³ of high-purity liquid scintillator was measured at (1.94 ± 0.09) × 10^-18, the lowest ¹⁴C abundance ever measured. At this level the spectroscopy of low-energy solar neutrinos, in particular a measurement of the ⁷Be neutrino flux, will not be obstructed by the ¹⁴C β decay intrinsic to a liquid scintillator detector. A comprehensive study of the deviation of the shape of the ¹⁴C β spectrum from the allowed statistical shape reveals consistent results with recent observations and calculations. Possible origins of the ¹⁴C in the liquid scintillator are discussed.
