Using an 185-kg NaI[Tl] array, COHERENT has measured the inclusiveelectron-neutrino charged-current cross section on ${}^{127}$I with neutrinosproduced by the Spallation Neutron Source at Oak Ridge National Laboratory.Iodine is one the heaviest targets for which low-energy ($\leq 50$ MeV)inelastic neutrino-nucleus processes have been measured, and this is the firstmeasurement of its inclusive cross section. After a five-year detectorexposure, COHERENT reports a flux-averaged cross section for electron neutrinosproduced at a pion decay-at-rest source of $9.2^{+2.1}_{-1.8}\times10^{-40}$cm$^2$. This corresponds to a value that is $\sim$41% lower than predictedusing the MARLEY event generator with a measured Gamow-Teller strengthdistribution. In addition, the observed visible spectrum from charged-currentscattering on ${}^{127}$I has been measured between 10 and 55 MeV, and theexclusive zero-neutron and one-or-more-neutron emission cross sections aremeasured to be $5.12_{-3.1}^{+3.4} \times 10^{-40}\mbox{ cm}^2$ and$2.2_{-0.5}^{+0.4} \times 10^{-40}\mbox{ cm}^2$, respectively.
