Description
Low energy neutrino-nucleus interactions can produce excited nuclear states that can de-excite via neutron emission. Neutrino-induced neutrons (NINs) produced by neutrino interactions on common gamma shielding material, such as lead or iron, can pose a background for coherent elastic neutrino-nucleus scattering experiments. Additionally, NIN production on lead is the primary mechanism for the Helium and Lead Observatory (HALO) to detect supernova neutrinos. The NIN cross section is expected to be large, but the process has never been observed. Results will be presented from five years of data collected with COHERENT’s Lead Neutrino Cube detector, including a limit on the NIN cross section for lead.
