Iodine is one the heaviest targets for which low-energy (≤50 MeV) inelastic neutrino-nucleus processes have been measured, and this is the first measurement of its inclusive cross section. After a five-year detector exposure, COHERENT reports a flux-averaged cross section for electron neutrinos of 9.2-1.8+2.1×10-40 cm2. This corresponds to a value that is ∼41% lower than predicted using the MARLEY event generator with a measured Gamow-Teller strength distribution. In addition, the observed visible spectrum from charged-current scattering on I127 has been measured between 10 and 55 MeV, and the exclusive zero-neutron and one-or-more-neutron emission cross sections are measured to be 5.2-3.1+3.4×10-40 and 2.2-0.5+0.4×10-40 cm2, respectively.application/pdfenIn CopyrightArticle - Refereedhttps://doi.org/10.1103/PhysRevLett.131.22180113122Link, Jonathan [0000-0002-1514-0650]381013571079-7114
