Abstract

Cosmogenic isotopes ⁹Li and ⁸He produced in the detector are the most problematic background in the reactor neutrino experiments designed to determine precisely the neutrino mixing angle θ₁₃. The average time interval of cosmic-ray muons in the detector is often on the order of the lifetimes of the ⁹Li and ⁸He isotopes. We have developed a method for determining this kind of background from the distribution of time since last muon for muon rate up to about 20 Hz when the background-to-signal ratio is small, on the order of a few percents.
