The background that appears in spectra acquired by the chopper spectrometer 4SEASONS at J-PARC was investigated. A continuous background that oscillates in synch with the rotation of the Fermi chopper was observed even when neutrons should be suppressed. The characteristics of the background strongly suggest that high-energy delayed neutrons continuously emitted from the mercury target are its cause.
