Abstract

A first study of neutron tagging is conducted in Super-Kamiokande, a 50,000 ton water Cherenkov detector. The tagging efficiencies of thermal neutrons are evaluated in a 0.2% GdCl₃-water solution and pure water. They are determined to be, respectively, 66.7% for events above 3 MeV and 20% with corresponding background probabilities of 2 × 10^{- 4} and 3 × 10^{- 2}. This newly developed technique may enable water Cherenkov detectors to identify over(ν, ̄)_e's from astrophysical sources as well as those produced by commercial reactors via the delayed coincidence scheme.
