摘要Cosmogenic isotopes Li-9 and He-8 produced in the detector are the most problematic background in the reactor neutrino experiments designed to determine precisely the neutrino mixing angle theta(13). The average time interval of cosmic-ray muons in the detector is often on the order of the lifetimes of the Li-9 and He-8 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.
